Early stage "Simplex" to Martin Evans' design, comprising a rolling chassis with quartered wheels complete with crankpins on axles running in gunmetal axleboxes and horns, pump eccentric fitted, smokebox saddle machined, three buffers machined and fitted, part-machined buffer remaining to be fitted.
Machined work comprises:
Set of gunmetal cylinder castings.
Blocks bored, faced, ports cut, passages to be done. One block has a small blow hole at one end in an insignificant place, shown on the closeup photograph.
One valve chest, valve and valve rod machined, complete with cover, other to be machined.
Axle pump complete with rod and strap
Machined chimney and petticoat pipe
Set of reclaimed drain cocks, used but useable
Set of hornstays and springs
Completed motion bracket and some parts to fabricate the other
Smokebox with door, locking handles, front and rear rings, machined for steam and exhaust pipes beneath, chimney on top. Rear ring rivetted, front drilled for rivetting.
Unmachined castings include:
Coupling and connecting rods
There is a piece of copper tube for the barrel, cut to length and with the dome hole machined, along with a set of flanged plates.
Complete with a new, unmarked set of drawings and a fairly clean copy of Evans' book "Simplex - a simple freelance 0-6-0 locomotive" giving blow-by-blow instructions for the build.
Can't imagine there's anybody on earth who doesn't know what a Simplex looks like by now, but there's some pictures of a decent one in the archive.
