This Andrew Barclay is one that I have built for use on the latest small layout that I am currently building. It started off as an out of the box RTR Hattons model and has been altered quite radically.

It is based on one that was built in 1913 for the Dalmellington Iron Company. The prototype had to work through a tunnel with just 9ft clearance to the crown of the arch and so the footplate was dropped, a canopy was fitted in place of a cab and the boiler fittings were cut down, with the safety valves being relocated from the dome to the first ring of the boiler.

The Hattons model is of a later type with a higher pitched boiler, so I had to lower that. I also milled the chassis block to allow the footplate to be dropped and milled the buffer blocks from brass to add weight as the new layout will have some severe gradients.
The plastic handrails were wrong for the period and so have been replaced with brass wire and ball-type pillars. The sandboxes were also replaced as these too were wrong for the period. The chassis block has been milled to make space for a Stay Alive and as the original motor would no longer fit in the reduced space left by lowering the boiler it has been replaced with a small coreless motor. A 15x11mm speaker and a Zimo MS490 decoder are also installed under the tank.

I have weathered the frames, motion etc. but cannot weather the rest as I am waiting for some custom lining and lettering decals.
