These could both be either Vasart (56 to 64) or Strathearn (65 to 80, but earlier years more likely). With canes standing well out of the ground, Vasart may be a better bet.
Under UV light, they could only be separated as pre-56 (i.e. Ysart Brothers Glass) or later. I suspect that these would not show as Ysart Brothers period - but without doing the check, we can't say for sure.
Regarding canes, we should remember that many seen in Strathearn weights were actually made in the Vasart years. And some were even from the Ysart Brothers time - or even possibly 1930s out of the Moncrieff period! For example, I think the central cane in the blue ground weight is one from the pre-1956 time.
Richard More's site ( http://strathearn.smugmug.com/
) is much better than mine for comparing Vasart / Strathearn weights.
