I have listed one of my two Model F ashtrays on eBay. Don't see any reason for keeping both of them. These are pretty rare. Electrolux made far fewer of them than either the XXX or G ashtrays since the F was made for such a short period of time - only about two years.
I've often wondered how many different models of ash trays and banks Electrolux made. As for ashtrays, the only ones I've seen are the XXX, F and G. And there are several different types of G ashtrays, in both turquoise and bronze. The fanciest one has the motor unit and power nozzle on it. I don't have one like that; I've only seen one in a photo.
As for figural banks, the ones I've seen are G (both colors), 1205, GoldenJ, Olympia, Silverado and Epic. Wonder if there are any others. I also have a model XII bank that's made to look like a miniature leather book, with an illustration of the XII dye-stamped into the cover, and an XXX mechanical bank with an illustration of the XXX on the front of it.
