    Not sure if this is going to post even...

    Hi everyone, I have collected my first Marlin from it's original owner who had laid it up for about 25 years in a wood. I dragged it out with a winch, still on the trailer which returned it from a failed MOT all that time ago.

    This is thought to be the 18th Marina Marlin kit built and used a 1275 van as the donor. I was involved with the original build, back in the early eighties, doing the wiring and helping with various welding and assembly tasks

    I first started this project about a month before Easter this year. Have spent several weekends gradually prepared the car for it's extraction from the woods. Two weekends ago we finally winched it out, dragged the car off the old trailer and lifted it onto a borrowed trailer to take to temporary storage until I resolve the V5 issue. (it doesn't currently have a V5, it's lost by the PO).

    The car is in a bad way, very rusty, and everything is rotten. The back axel is rusted through and leaking EP90. The fuel tank disintegrated when I tapped it to check for fuel Fire risk? NOT. The engine is seized rock solid, coolant pipes fallen apart and perished. I can't shift the gear lever. The wheels go round now after much persuasion with a big hammer. The only good thing I have discovered is the oil level is normal and the oil is clean.

    A twist to this tale is that while I was researching Trials Marlins (I want to trial it) I recognised an old friend of mine who it seems has been very successful trialling Marlins. I contacted this old friend, it turned out it was him, and to cut long story short, he no longer competes with Marlins. But, he still has an un-started project, a Triumph based kit which has never been completed or run, which he had intended to re-build one of his highly successful cars onto but I suspect the impetus of youth has waned a bit.

    Apparently it was fitted with a Ford engine and gearbox but no front suspension or steering?

    As part of the deal i have gained 27 tyres and some assorted wheels. Four brand new doors, two steel, and two aluminium, and three rear Marina axels, one close to new. I have discarded the diff and casing because the teeth were badly pitted, both the crown-wheel and diff pinions. I have kept the half shafts and brakes which are perfect. There is also most of a smoky 1800 B series engine. I collected the parts and tyres this weekend, about 230 mile trip.

    Next weekend I plan to trailer the rolling chassis back. I will probably have some parts surplus, so once I have established what I actually need I will make the surplus available to members here. I don't do fleaBay any more.

    There will probably be two rear wings one new and un drilled but both are a bit damaged but repairable. A new rear body with the spare wheel area dished for the wheel, drilled but unpainted. Possibly the windscreen cover panel inside and out, both new. Two pairs of doors, and some other parts, inc Marina Discs, suspension and other misc bits and pieces.

    The project will slow again while I apply for the V5, in the mean time I need to learn some about the Triumph chassis differences compared with the Marlin chassis. I also want to weigh up various features of the Marlin and try to understand them better.

    I have noticed the front of the chassis on the Triumph design is very different from the Marina design, the differences are far greater than simply the suspension mounting points. I need to understand how the Marina body parts will interface with the Triumph chassis.

    If anyone can comment on this I would appreciate it. I am planning a spartan trials car build using the A Series motor rebuilt, the body from the black Marlin and the new Triumph chassis. Simplicity and light weight being the overriding features.

    Theres another thread on here that I think Steve Green posted with some chassis measurements. I dont think one setup is interchangable with the other - in any case the triumph herald bits are probably easier to get hold of

    Thanks for the info Cameron, I have searched but not found.

    Once I have a result with the V5 I will strip the Marina car completely and create a CAD drawing of the critical areas of the chassis. If anybody can post a link to the post I would appreciate it. From what little I know of the Marlin it seems to me the radiator cowl and the flat aluminium parts either side of the engine bay will be different but maybe the front wings will be the same?

    I plan to alter the engine side panels making them removable and making louvers for improved cooling. Possibly louvering or making vents for the bonnet too.

    I think the rear end is Marina, just like my other chassis. As soon as I get the other chassis I will post the chassis number so perhaps we can identify it.

    Hi that looks like quite a project.

    Good luck with the V5 and Road Tax. Even though the car has obviously been off the road for several years before SORN was introduced, so no Road Tax reminders whould have been sent, the DVLA if in an obstructive mood, will demand the outstanding tax. That was pretty much the reaction I got until I took a large file of old MOT certs, photos etc etc to the loca DVLA office and saw someone face to face.

    I do not have a dimensioned drawing, only a copy of a drawing from Pitstop. Its posted on the Marina Roadster Group page.

    From my limited understanding of Triumph chassis and body none, if any, of the front body parts are interchangeable and I doubt that the rear is the same either unless your car is a Hybrid that I rather suspect it might be.
    The person to ask is probably Ben Caswell, the Triumph Rep.

    If the rear axle is a beam type the chances are it's Marina but if the donor was a Marina van, this could be a Van axle, much sought after by the Trials drivers as it has a much higher ratio. Over on KeepAndShare, I have shared copies of BL Workshop manuals that will help you identiy the axle at http://www.keepandshare.com/doc/4204...1-pm-631k?da=y and http://www.keepandshare.com/doc/4204...1-pm-671k?da=y. You have to register and become my 'friend' to read them. A quick and FREE process.

    Hope that all helps.

    There is plenty of Tea around here Steve so I live in hope this works out.

    Fingers crossed on the road tax. Up to now DVLA have been very helpful, let's hope they stay that way for the critical bit.

    Thank for the info, I should have the second rolling Chassis by next weekend so I can start measuring for myself. While I can see there may be some differences particularly the upswept front chassis extensions, I would have thought I could cobble something together. This is to be functional, not pretty. If I have to pop rivet some bit's of aluminium in here or there, so be it.

    I think the axle on the first Marina Marlin will be a van axle, the PO warned me it's very skittish in the wet, possibly because of a low axle ratio? I know they are pretty light too, so it may be a combination of low ratio and light weight. However it isn't the sought after axle because they have a larger PCD, 4.5 inch I think (same as MGB?). This axle has a PCD of 3.75 inch - so must be Marina or similar.

    The second new chassis definitely has a beam axle believed to be Marlin so yes, a hybrid. One of the things which has been puzzling me is the mounts on top of the Triumph suspension turrets, The PO and I were trying to figure what they were for but I think they were for the Triumph engine mountings, I think some sort of strut brace might be good there, might double as a radiator mounting perhaps.

    Occasional trials, I really want to do the Lands End, but the logistics may challenge me, living in South Lakeland. I have spectated on the Lands End many times. I have done PCT's with Morecambe Car Club years ago. Have driven diggers and excavators all my life so have a feel for the rough and slippery surface. I can't afford to compete big time but just something to keep me amused and active really.

    I knew of this Marlin and that it had been abandoned in my friends wood for many years, I saw him last year and just asked if he still had it. Then before Easter this year I popped up to his place, I got out of the car, he was feeding the chickens, "You come about the Marlin?" he said! 'Well yes!' was my reply. "Take it if you want it" So I have but he has lost the V5. He thinks he still has the original V1 log book but he can't find that either.
