  1. Eloquent as ever Clive........ totally agree as most of the piles of rust that sit waiting their turn in both mine and my sons workshops pay testament to.......all I have to do is live to be about 120 and I should have them all finished :nut:

     

    Pete

     

    Just print me a teeshirt with that on Pete, and I'm stuck here on my own ...

  2. Are you still allowed to use the vacuum system?

     

    I'd think you'd have a lot less problems with modern compliance on a vacuum system. If the vacuum fails or the 'trailer' disconnects for whatever reason, brakes come on and stay on - job done. Only wrinkle there would be if ALL the wheels aren't braked.

     

    Worth noting that there are a load of exemptions for old trucks, but very few for old trailers. Only trailer legacy compliance points I could come up with is that the original trailer lighting systems are bound to be compliant if they are exactly the same as when they left the factory and were first used. Of course you'd need a serial number on the trailer or plate to establish the date of first use ...

  3. There's two points here.

     

    Adrian is right about the generic similarity as to the original setup, but there are a pile of little wrinkles about using them on UK roads today, if that is where you are heading.

     

    First you have the trailer regs about weight, braking on each wheel, etc, then you have the limitations about using electric brakes in the UK now. As examples, they must work automatically ( adjustment from the drivers position isn't allowed ) and they must have a power source on board the 'trailer' that can bring it to a halt automatically if it disconnects at the wrong time, and when that power runs down it shouldn't be able to roll away again. Basically you need a small battery and an automatic controller on your 'trailer' and some provision for an effective handbrake. Absolute 'compliance' might be really tricky, but if you could demonstrate that you had an effective automatic system that was really, really close to the requirements you might get cut some slack if you get a roadside assessment. Emergency stop from 50mph behind a GMC might be - interesting.

     

    I believe all the technicalities can all be overcome, but it is tricky. Best plan would be to get an understanding of exactly how the originals worked, then to google 'electric brakes uk' or the like and look for fora where people like the Airstream caravan groups have already tackled this for similar systems.

  4. Yes, that's the one. Dalzell Steel.

     

    Did some work there when it was younger. You could still see the infrastructure going back before WW2, and there were tracks for horse-drawn service trollies - clearly not big enough for motorised transport.

     

    That same plant is now setting up to make steel for the new river Forth crossing.

  5. first layer was grey by the look of it, covered with olive drab,

     

    That's factory primer and finish. It would have had hood numbers too but that's it.

     

    You can look for shipping or preservation stencils, bumper codes.

  6. It's a Sno-Trac by Fisher Aktiv I think, and that one probably isn't military.

     

    There were a bunch of them with canvas tops used by the military, and the forces probably had some hard tops as well, but mostly they seem to have been civilian. VW Beetle power plant, nice thing, worth having if in good condition and the right price

  7. That engine and box is a bit of work, isn't it?

     

    It looks like HALLEY built the whole thing then ( having Glasgow on the side of the block ) Chances are it was only fitted to their trucks, patterns will have been dumped nearly a century ago, not much chance they were fitted to other trucks or for other uses as they would be expensive to make in limited quantities.

     

    I can only think of a few possibilities. Transport museum in Glasgow may have information or exhibits, failing that the most likely places for survivors are on top of a mountain in New Zealand or in a dusty bit of Australia.

     

    Still, given the talents and skills shown, no big deal if you completely restore the whole truck less engine and box, do a temporary power train, then left the result waiting for an original to turn up.

     

    Lovely job

  8. I can only provide negative help here.

     

    It looks to be big, simple, and of US manufacture. All the WW US units I've seen have been much more complex in design and more technical looking, so if I had to guess it would be from an M series vehicle, but that's it.

  9. & they would have to be 150 ft AGL as the vehicle would fall at the rate of 100 ft/sec.:(

     

     

    ... reminds me of an illustration in one of Fred Crismon's books. It was a big US jeep with a recoilless launcher that was actually capable of launching a small nuke. Range of missile was a a few miles, somewhat less than the blast radius of the device ....

     

    Still, deviating from subject here, next item please :cool2:
