Yellow Crinkle/Bark/Ice Tumblers

I have a set of pale yellow crinkle or bark (or ??) old fashioned tumblers. I know a few co.'s made similar but trying to decide who made these. The rims are cut/polished.......and they are from 1977.

The base is moulded, so no pontil. It is slightly concave - but not much at all. The inside walls don't have a 90 degree angle at the bottom - they kinda slide into the lowest point in the center - picture a skateboard park 'bowl'... LOL

They are 3 1/2" tall, 3 3/16" outside diameter at the rim.

Can anyone tell me anything about them?

I apologize that the pix are so large.... I thought I had resized them correctly, but obviously not.

Could it be Whitefriars? Thought it might be Ravenhead Glass, but checking the whitefriarsglasswannabees webpage there are two bark-effect tumbers side-by-side and it's looks very like the Whitefriars one on the right.

Thank you, Naomi, for your reply.

A few people have suggested Whitefriars but others who collect WF have said they didn't make tumblers in color.

In addition to WF and Ravenhead, I've looked at Ingridglas and Iitalia. Whitefriars is the closest I can come. But then there is that pesky yellow color! LOL

There was some discussion that these glasses may be Italian, they look very similar to some Whitefriars glasses but come in several colours not used by Whitefriars. Bit of a mystery really...

Thank you for your reply, John...guess I'll just list them as unknown maker. I appreciate you taking the time. :)

Thank you to everyone who checked my question!
