Dunlop Jig-Saw Puzzle Series, The

Series of twelve known plywood promotional jigsaw puzzles from Chad Valley, produced in association with Dunlop Rubber Company, all showing a Dunlop logo in the picture, usually on a vehicle tyre, or in the case of the Westminster Bridge puzzle, on the stairway of a bus.
I was fortunate to recently acquire the puzzle which is generally accepted as being the least common example, that of O.H.M.S. Air Force, which is featured here. I would very much like details and images of the others in this excellent series, so if you are able and willing to contribute, please contact me. Many thanks.
Several other examples appear on the Jigasaurus, but as they are in non-Dunlop branded boxes they are not included in this promotional album. Two such examples are: Liverpool Landing Stage and Westminster.
