I have what I believe to be two prototype models of two of the early planes made by the Dart aircraft Co. Dunstable. the open fuselage example is the Flitiermouse, correct reg No.; only one ever built and a Dart Pup, again only one was ever built. If they were made by this company they are probably very interesting pieces of that companies history of which little is know about, as far as I can tell. Any further info on these please? These models are well made from wood & metal and came to me with two others, one being a Slingsby type glider. I believe these were made just before the 2nd World War as models, around 1936. Flittermouse around 24 inch wingspan; Pup is around 18 inch wingspan.
