Union Jack Series

This set of six interlocking cardboard jigsaw puzzles are of unknown manufacture, but thought likely to be of British origin. There is some likeness in box label imagery/terminology to this G & P puzzle, which is believed to have been by Gale & Polden, although the puzzles themselves are entirely different, so here the similarities end.
This Union Jack set of six images features postcard-sized images of:
H.M.S.Bellerophon by Symons; H.M.S. Collingwood by Cribb; Black Watch-42nd Highlanders by Stewart; Scots Greys and Dragoons, also by Stewart; French General Paul Pau by Topical Photo; and Indian Troops for France.
