1930s wooden jigsaw , hand cut and marketed by Chad Valley-this puzzle and a series of about 30 were made for the Great Western railway and sold on their station platforms ( for I think 2/6d old money ) -the subjects of the puzzles tended to be  of places where the GWR trains visited. This one is of one of the locomotives used by the G.W.R
 Box original =all complete . The puzzle is amazingly bright and has been well cared for. VERY tricky to do I might add
Puzzle is  All original and all complete with no replacement pieces . Box is pretty good
  Collected by both jigsaw puzzlers and GWR enthusiasts. POST FREE to UK
