Yes, both appear to be Paul Ysart weights.
I would like to see separate, larger images of each weight just to see the cane details better (it's a fascination I have). Also, could you please show a photo of the base of each - at a slight angle as the features may help to confirm the dating.
And one more request, please ... an image showing the "caithness 1962" on the left-hand weight would be useful. Most reference works on Paul Ysart state that he joined Caithness Glass at Wick during 1963.
