"S.S. Don Charles" A Spot the Bits puzzle.

The maker of this curiosity is not known. It was probably made between the late 1930s or early 1950s. It had been exhibited somewhere as demonstrated by the now illegible label which is attached to the accompanying instruction notice.

Here are the instructions and large enough photos to find most of the bits.

(If you happen to know the maker, please let us know. It is accompanied by an Exhibition Ticket so must have been seen somewhere by many people. Purchased at an Antique Fair in Somerset UK 1990s)

We would also like to know of any other similar objects.
