Due to an order for something I didn't already have, this 1930s LMS Loco Crew have appeared in the last few days. Converted from castings of my LC4 set, these ones have the extra feature of separate heads.
Before the recent diesel drivers figures I thought separate heads too fiddly but I was proved wrong and this will become a feature of any similar sets.
I think I will probably add a 'flat cap' option before they go into production.
