This shape is used very rarely by steam railway jigsaw puzzle manufacturers but such examples attract more attention when assembled on a family table top. I have used two examples in previous posts and here is a picture of another (26th June 2011) - I only have four in a collection of around 400 steam railway jigsaws.
The puzzle was retailed by W.H. Smith but I'm sure its manufacture would have been outsourced. The puzzle is of 500 pieces, reproduced from a Rob Johnson painting. A small, Southern railway 0-4-4 'M7' tank engine, No.60, designed by Dugald Drummond is pictured on a level crossing in a very English country village. Thatched cottages, country gardens, a hay cart, an old Royal Mail van and a few local people add interest to a superb picture.
