I'm presuming this frog is original , were these frogs made by multiple manufacturers like the ww2 counterparts ? are any maker marked ?
Thanks

The simple answer to both your questions is yes.

Somewhere I'm sure I've seen a list but at present I can't remember where it is !

I will have a dig round.
