Square base glasses

Clearing our our glasses cabinet- are these keep, sell or scrap?.
They’ve been lurking there for years and we need the space. Smaller ones are sherry glass size.
I only thought they were unusual as they have a thick square base but maybe not?!
Any thoughts?
Thankyou

 

Anyone?

 

the photos on replacements, but maybe this one, unknown 8625

Thanks for looking. It does look very similar. Shame they don't know any more about them. I may just put them on eBay and let them find their own value.

 

This is to add information, not identify this particular piece.

Hawkes cut glass made square bases on some of their stems. I found this buying old stock from the Tiffin Factory after it closed, they had purchased the franchise from Hawkes and were making and selling stems identified as Hawkes. Some I bought had square bases.
