Topic: Crystal ? Cut Glass Grape Engraved Cups for ID Walsh?

[user9318]

I have had this glass cup for a number of years and wondered who made it or how old it is.

It has a cut diamond / cross design with engraved grapes and what looks like wheat or maybe barley. Typical ear shaped handle, which you can see where it has been attached.
Star cut base.

Height 2¾"
6.8cm maximum / top rim diameter

I have searched ebay and google recently and in the past to find a match, even just to find the exact same cut pattern to no avail. Any help in the identification of the maker and age would be appreciated.
