Just finished assembling 25 working reverser stands. Black handle in BR days, red in the SR and LSWR period. The Brassy rivet will be flattened and painted black. Not straightforward in any way and almost every part needed fettling and adjustment to give them free movement. About 1 hour each on average!! and here is a close up showing Chris Tolhurst's exquisite pattern making (n0 3D printing here!). You can see the locking wheel and the locking lever all beautifully modelled.
