I had thought Davidson initially, with a possible date of early to mid 1920's, or alternatively the late 1930's when black was re-introduced - but I don't know if they produced matt black at this later date. This piece might also be missing a stand and/or flower dome - really not sure. Diameter is about 152mm - 6", and unfortunaely, the mice have started slightly on the rim. If one of the Davidson people can confirm or deny, I'd be very appreciative, and thanks for looking.

I've started with the post here, even tho it may well be English - and if so then grateful if the mods. will move for me.
