Update,

The replacement sprung buffers have a small cap that needs to be soldered in place, but once that is done I found that the components were not supplied with a back buffer plate, and so I had to make my own. I did lose a cap but I made my own.

The following photograph I recieved from Tom Biddle (A.K.A Blue Pioneer), and may I say thankyou again, for it is a great picture. For a while I've been debating with myself whether or not to discard the 'enclosed' coal rails that came with the kit or make some myself to represent the earlier 'open' type you see. Prototype photograhs show both types so it seems it's a case of location and time period.

The following progress isn't to my eye perfect but it is I think good enough for now, and for the top rail a second attempt. The first wasn't bent outward enough. The second still isn't but better than it was.

The picture below, showing the 3 middle posts to be wider. What I've used isn't wide enough I don't think but it's all I had to hand and I think underscaling is sometimes better than overscaling anyway. You will notice that inbetween the 2 rails there is in fact a 3rd that goes part the way through. The original plan was to add this also but since it seems I'd need thinner wire without it looking enclosed I decided to leave it off. Truth is, This is the only deicent photograph I have seen of the back and so I do not know for sure whether there was more than one design.

Good thing is there is nothing stopping me adding the other rail later if I decide to.

This is what I did, followed by two rails on the out side.

And a jumble of views in attempt to save space and clutter.

Although not bang on, what you think?

Maybe get some thinner rod and redo the outside rails, including the 3rd because I think it's a little fat.
