The loco was built from a very old version of the Brassmasters kit that I picked up from a 2nd hand stall.
The loco is fully sprung using BM/Comet coil spring hornblocks.
Motor is a Mashima 1420 mounted vertically in the firebox and driving the rear axle through a Branchlines 38:1 gearbox.
The tender is also fully sprung using continuous springy beams.
