Buying figures in 7mm is exciting. Yes, it costs a lot of money, but not that much more than you shell out for decent 4mm figures. The great thing is that there are some really nice miniature people out there.
My choices are, on the left a driver wearing a bowler hat from S&D Models (OF23a). To the right, engine crewman mopping brow from PLM cast-a-ways (C300).
Costs are £3 and £2.20 respectively.
That extra 80p buys much finer detailing and sharper moulding. Whether that matters to you probably depends on the loco the little man will be stuffed in to. The driver does have a posable arm, although I had to vandalise it so he could look out of the Y6 engine window. The result is a bit odd (ad fell off as I took the photo, hence the dodgy superglue repair.
I didn't notice the difference in height until the photo was set up. It's not a big problem and will be even less so when they are at opposite ends of the engine.
The S&D range is very impressive though. Modelling as good as the Monty's range in 4mm scale. Even if I didn't have a loco to fill, I enjoyed painting him immensely.
Modelling note: Both figures were primed and painted from the Humbrol range. A final coat of Railmatch weathered black deepened the shadows and added some footplate muck.
