A well-made example of Martin Evans' "Springbok" design for an LNER B1.
Work to date comprises:
Rolling chassis, wheels accurately quartered and dowelled, front
bogie complete, coupling rods fitted
Gunmetal piston valve cylinders machined and fitted, complete with pistons, valves, rods, guide bars and crossheads
80% complete tender
Sundry small parts, including twin ram mechanical lubricator, dome, brake components, buffers etc
A large, powerful engine when complete - many have been built to this well-proven design. There are some pictures of a complete one I have here.
