Topic: Need help authenticating Kerr Wood Grain Drinking Glasses

[saidthegirl]

I recently purchased five drinking glasses from a resale shop that have a tree bark/wood grain design. They measure 7 3/8 in. tall and about 3.5 in top diameter (2.5 in. on the bottom). The only markings on the bottom of the glass are numbers, such as 15 or 9. I've attached a picture.

I did some online research and I found the exact same glasses made by Kerr in the 60's, but the measurements do not match. All of the Kerr's I found were 6 in tall. Check out this Etsy link for reference:

I would like to know if anyone knows if Kerr sold the tall 7 3/8 version, or what other company might have used the same design to make the 7 3/8 version. I am looking to complete my set!
