This came from a box of assorted bits that belonged a modeller who has passed on, so is obviously unable to tell me what it is.

 

The sides and ends are not cast whitemetal.  They might etched zinc, although having never seen the stuff before that can be no more than a hunch.  It is certainly thicker than any etched metal I've seen before and is backed with what appears to be dark green vinyl (The purpose of which also puzzles me)

 

If the majority of the other stuff in the box is any guide, the previous owner's main interest was the LNWR.

Having had a very close look under a magnifying glass, I'm going to stick with saying its etched.  They might be thicker than etched brass or nickel silver, but they are still much thinner than any casting I've ever seen and they are slightly springy, like sheet but unlike castings.

 

Edited to add that although it's thicker than conventional etched brass or nickel silver, it's also rather lighter.

Definitely Trevor Charlton. He used to list a large number of coach sides and in the days when I modelled LNWR I had a number of these. I presume that Trevor no longer lists these ( assuming he is still around). Not sure if it's a 4 or 6 wheeled underframe but London Rd Models can probebly sell you An appropriate under frame.

The zinc I think was used as the sheets were used in the printing trade. Phillip Millard did some similar etches but they were only half etched out, so you had to cut out the outline with a fretsaw. I think with changes to printing the zinc sheets are no longer available.

I believe Trevor died a few years ago.

 

I'd say from the length it would a four-wheeler.  Presumably a full brake intended for branch use?

 

Any ideas re the purpose of the green vinyl backing?

And, having never met etched zinc before, how do you use it?  Conventional 145 solder and flux?

100 mm =25ft I thought I would have a quick look in the illustrated history of LNWR coaches. After a quick look I can find only 4 at 25' long d426 pacel van d447or 463 covered carriage truck. W108 fish van. No drawing of any of them. I keep looking in case I missed something

No chance

 

A specialist soldering task:

 

Flux - http://www.superiorflux.com/soldering_flux_for_zinc_metal.html

 

Solder is a problem best is an alloy of Cadmium and Zinc (It is lethal! stuff Cd is very toxic and basically do not use it, fume hoods and that sort of protection) The more usual solder for aluminium may work as well.

 

The problem is that Zinc reacts with just about everything and forms a insoluble protective coating, which then resists the solder from "sticking" at the molecular level. You might get some progress with low melt solder effectively a "gluing" process.

 

But if I were you I would just use Araldite - is it really worth specialist solders and fluxes for one kit?

I've dug out an old Trevor Charlton price list (Why do I keep these things?) and looked at which 25' coaches he produced.This looks to be the likely candidate

Midland railway Dia529 brake van, now produced by 51L. All the panelling seems to match up etc.Very nice it looks too, I must get one
