I'm hoping this is ABP from the beginning of the C20 - previously pieces of what I thought were this turned out to be Czech from 1950's!
Seems to have all the right features, but regret I can't find the pattern in my one and only book, so perhaps someone from the other side of the pond is able to recognize the design.
The saw tooth rim is moulded , but everything else is cut......... the mitres are deep - the handle looks right especially with those lenses, and the robust squat shape looks o.k. for the period.
The prismatic cutting under the lip is a much older feature, seen often on Georgian/Regency pieces, but probably never gone away.
About 3.25" at the tallest, and heavy for its size. Unfortunately, it hasn't travelled well over the years, and the pix belie some extensive general wear, but since I so rarely see any ABP, I would have kept it for reference anyhow. Of course, I might still be wrong and this could also be Czech.

thanks for looking.
