Hi. Agreed - I think very few -if any - Strathearns can be dated by the canes (other than those with a specific date cane in them!) and the other, more general canes in those got used from year to year. I think some of the earlier pieces may share some 'late Vasart' canes, but that is about all you can say - and distinguishing late Vasart and early Strathearn is well nigh impossible anyway! I have had lots of the closepacks like yours (and spokes), and never really found much to help tie them down to a date.
