This is the diagram 42/84 6 wheel Lav Compo of 1882. The carriages - there were 2 of them - lasted until 1918 or 1920 in use and then one of them, no. 272, became a 'lobby' at Norwood. This again is a test etch built upto check whether it worked! I'll actually be getting around to getting castings and selling kits soon!
