Keith - That "other similar" weight is also a definite Strathearn. As well as the space around individual cnaes, another regular feture is the use of a "very coggy" outer structure to many of the canes.
John - Thanks for the size info of those weights in the Peter Francis auction.
General info on the Peter Francis closepacks:
The larger of the two has about 150 canes and most appear once only.
The canes in the larger closepack include a single example of one of a few designs of "Ysart butterfly canes". The smaller closepack has about 90-100 canes but has no butterfly, or other "Salvador special canes". Although I have yet to make a full analysis of all the canes from both closepacks, I can confirm that a few are new to me but the majority are ones I have seen before in "Salvador Ysart / Ysart Brothers" items.
I therefore believe that both closepacks were most likely made by Salvador Ysart, And I would date them to the Ysart Brothers period of 1946 to 1955.
But ... a check under UV light (both longwave and shortwave) might prove me wrong.
Point of note:
Many people still consider the example butterfly cane in the larger closepack weight to be a "Paul Ysart cane". And that may be another reason, besides the presence of the concentric PY weight, why the hammer price for the "Lot of 3" was higher than some folk would have expecetd.
However, that particular butterfly cane is known to have often been used in weights from both Paul and Salvador. It can also be found in a few weights that I believe were made by Vincent Ysart at the Vasart Ltd company (1956 to 1964).
