Hi Mike, firstly I never initially commented on the weight because I thought enough had already been said and the general consensus was that it wasn't so didn't really see any point and anyway I know nothing about paperweight in general.
Really I just added the comment because I thought it unnecessary to add ID = Not a known Whitefriars which I thought just added confusion? and even implies it could be a either an early piece, maybe uncatalogued or even a 'frigger' piece.
So really was just asking the moderator politely why the 'add on to the title and why it was just not left as an enquiry post till any further if any information came to light?
Anyway back to the weight, Whitefriars early amber, last part of the 19th / early 20th century was indeed a brown darker amber, most of the catalogues available from the onwards show amber in the colour range which was known has gold amber from around 1920 which was Selium based and had a definite orange colour after the war the name appeared to change to golden amber till around 1962 when it appears to have been discontinued and replaced in 1969 by tangerine.
I have been handling/selling W/f for 10 years and all the pieces I have come across from the 1930' onwards are the orange shade of amber and have never come across a known/labelled piece resembling this colour/style weight.
Have stated many times never say never because things do crop up from time to time and bite and bite you on the ars*
My honest opinion though is loads of pieces all the time appear from the '30s onwards and I am sure a weight of this style would probably be available with a label on and I have never come across one so my opinion is pretty sure it isn't.
Hows that for 'long winded' apologies for having to read all that but I am well knon to 'go on a bit'
Cheers and good luck with your collecting, it's never been a better time to start.
