Morning all,
as you know by now weights are not my usual thing

and unless they are signed or have other obvious ID features I'm pretty much stuck
however, in the paperweights unlimited chapter of the 20th century british glass book there is a plate with what looks remarkably like one of these.....can anyone confirm please?
windows are concave, weight is 424g 4.8cm tall x 7cm wide (approx)
many thanks
Mel
