3 inch scale Atkinson steam wagon

A well-advanced 3 inch scale Atkinson steam wagon to the Ray Prime design, serialised in "Engineering in Miniature".

Work to date comprises a largely complete engine which is free to turn over, rolling chassis and silver soldered copper boiler.

The boiler has had a twice working pressure hydraulic test at 200psi for 100psi working - structurally sound, although with several small pinhole leaks which will require calking.

If you need reminding what the finished wagon looks like, we have a truly superb example in stock at the moment, pictures and further details here.
