Personally I feel it would be nice if an open mind could be kept on this one.
I've added a shot of the dump with a Golden Amber example of a paperweight. Clearly the dump is not Golden Amber
The Golden Amber paperweight shows lots of wear (see last photo). If this was caused by using the weight on an oak desk then imagine what it would look like if used on a stone floor.
There is little catalogue information for the 1920's with Whitefriars Glass, also on page 228 of 'Whitefriars Glass' by Wendy Evans, Ross & Werner it states ' The 1928 stock lists and workbook together show the following basic colours'....'Amber , Light Amber' . Then the book on the next page indicates the colours recorded in the ' c1931 catalogue sheets are '....Golden Amber' with no mention of either Amber or Light Amber.
As I said above with the unpolished pontil scar , this could have been the norm with dumps of that period ; but I entirely agree it is highly unlikely for Whitefriars not to have polished the pontil , it is smooth though, so could have been heat polished.
Anyway , I've stated my case and I hope you can see my somewhat obtuse views on the matter :ow:
Thanks again for all the feedback and help. Ta Mike.
