It is very hard to identify and date the accessories accurately. Quite often there is no makers mark and all you can go by is the shape of the workman, the colour and shape of the base, the type of piston or flywheel and so on.
The trick is to find something that has already been identified either by being in a specific catalogue or on a website.
As I come across more books and website I add them to the ever growing list.
I use the help of friends from around the world and the following books, catalogues and websites.
