I don't get this! Two signed weights by Jack Allan, one signed "s" with a signature cane i've not seen before, ...
I think it is wise to make queries when something unusual happens.
For the general point of two "JA" signed weights appearing together in the same batch of items, it certanly is unusual as not too many signed JA weights have appeared on the market in the paste several years. However, I think it's all ok and looks like somebody happened to collect a range of weights that were made in the late 60s at Vasart and some had a "JA" cane (not an official inclusion, but occurred nevertheless).
But, regarding the "S" cane, would I be correct in assuming, cfosterk, that you do not have, or have not fully studied, Andy Dohan's book on Paperweight Signature canes? And perhaps you have not seen the Aug 2005 issue of the Newsletter of the Paperweight Collectors Circle. (If you are not a member of the PCC, you really should join - the full colour Newsletter is superb and well worth the membership fee on its own!
For the "S" cane, as well as being shown in Andy's book and the PCC Newsletter, it appears in Richard's website at this page.
Note the comments by Terry Johnson, who was the author of the piece in the 2005 PCC Newsletter. The complete Strathearn flower weight with that cane is shown in Richard's site at this link
and is very similar to the one in the Bergstrom museum which was the source of Andy's comments in his book.
The PCC Newsletter piece referred to my UV examination of Terry's weight which showed it to be before 1956 and therefore at least 8 years before Strathearn was formed out of the Vasart company. I also now have a concentric weight with the same "S" cane and this also fluoresces as earlier than 1956. In my weight the cane is set reversed so it looks more like a smoothed out "2" or "z"!
So, that "S" cane may
have been a true signature for Salvador Ysart, but was first generally noted by collectors in a later context of a Strathearn upright flower weight! Maybe that makes any weight with that cane quite desirable? And maybe these comments may now cause a sudden rise in the bids for that weight? Or maybe not - perhaps it really depends on how we all view the "niceness" of the weight.
