And here's another one shown in one of my non-paperweight web pages.I thought I had commented about mine in connection with Barbara's (as shown in the GMB link Anne gave above), but clearly not - might have missed it. Having checked mine again, I can see that I misread the date letter in the lozenge as a "C" instead of "G".
I see that Barbara's (same colour as mine) has a large chip on the top which might suggest the loss of the Cross as shown in the National Archives information for design 183953 (as per Ivo's link). I can confirm that my example has a simple point at the domed finial which is part of the mouled shape - much the same as Ivo's. Perhaps the glass versions were not produced with a Cross on top?
Another of these (in
opaque pale opalescent green
, I think) was shown a few years ago in a Glass Circle
/ Association exhibition,
"From Palace to Parlour", Aug - Oct 2003, at The Wallace Collection, Manchester Square, London. But no maker was stated.
