Thanks Kev
It was indeed Richard More's site that I used to do my basic research on these weights.
Thanks for explanation ref the 'Aladdin's Cave' - PP7 it all goes down in the databanks for future reference.
This is a lovely John Deacons paperweight of similar form, the diam is 3”

I have noticed an increase in cost for Vasart / Strathearn and early Perthshire paperweights on the high street and on web stores / eBay.
I guess as online databases, books and experts increase in quantity and the accuracy of attribution is now so good, it is having an effect.
The label is the thing - I do lust after it as a completest, but prices are always at a premium - the two Strathearn cost me £50.00 each (they are perfect).
The first paperweight I ever sold on eBay was bought for under £1.00 and sold for £130.00 back in 2002 to a Christie Saferite of the USA
The pictures are awful as it was less than a 1 megapixel camera and I didn’t know how to use it. Do you recognise the weight Kev
