Another Stemware Mystery - UNK 294

Hello everyone - These champagnes have me a little perplexed. I think I found them in Replacements Crystal Stemware book as UNK 294. But I can't seem to find them on Replacements site to confirm. Am I doing something wrong? I tried everything I could think of to get a shot of the cutting but no luck. It's grapes with leaf branches on either side. Thanks for any guidance.

Thank you Tallcakes. Why in the world are they using a UNKUNK294 format? How are you supposed to find unknowns? (Rhetorical whiny questions ).

I used unk294 (no spaces) for the search...
