Whirling Star and Cross Hatch Sherry ID: Maker? Pattern?

Okay, here I go again. I'm working again on my unknown stuff and such. My Mom had several (24) sherries stems. They have a whirling star cut on 2 opposite sides and crosshatch cut in some kind of an elongated/stylized triangle on the other 2 sides. There is a name for the triangle cut, but can't come up with it now. Nowwww these sherries **look** like cut-glass, but do **not feel** like cut-glass. The non-faceted stem has a notch/bump in the middle and the foot is plain. Dimensions: Stand 5" high, diameter 2¼" and 3 oz capacity to the top of the brim. These were bought sometime around 1970 by my mother. At that time she and my step-father were living in Galt, Ontario. That city has since changed its name tooooo..... ohhhh, I think Cambridge? My sister-in-law, a transplanted Canadian, believes she probably bought them in Canada because sherry parties were not uncommon up there. I have 12 of them and my SIL has 12.

I have search and search over the years with no luck. I bet I have done dozens of replacements.com searches. The closest I've come to similar ones are the "Star of Edinburgh" by Edinburgh Crystal. The big differences is that Edinburgh's star and triangle are not the same and it has a cut foot.

I know there are probably hundreds of nearly identical stems like these out there, but thought I'd ask in case someone was familiar with this pattern and/or maker.

TIA.
