If you haven't realised already I have a particular interest in Davenports apparatus and this post is going to look at three coin trays sold by them over the years. The above is an early advert for three of their trays, though I'm not sure which of the below were available then.
First up is a very plain plastic model 4 inches across. It has a gorgeous marbled green and black finish and is made of thermoset plastic (similar to Bakelite). It is very thin and has a card base. Not a wonderful quality item, especially as the gap between the edge of the plate and the slot is about an inch.
No such problems with this version though, probably their best known model. Fantastic quality in heavy red Bakelite. This is part of a series of three products in this distinctive plastic, all featuring the Demon head trademark, the other two can be seen at the bottom of this post. The action of this model is great and it looks like a stylish Art Deco ashtray or coaster.
The final (and latest) model I have is this thin tin tray, sprayed blue and with a silver paper star adhered to the centre. All of these models were sold separately and in magic sets manufactured by Davenports (such as the popular Maskelyne's Mysteries sets). This is by no means a complete list of coin trays they made, but these are the three most common.
