Hi all,
I'm an Aussie, who recently came across 2 Patrick McMahon wine glasses in an Op shop in little old Perth.
Thought maybe someone else might be able to tell me a bit about them, since I've found little info on specific pieces online

Appear to be of a duck and a crane, which (although both are birds) seems to be a bit too different for a pair of glasses, so I assume they may have originally come from a set of 6?
I don't have a pic of signature (I'll take better/more photos tomorrow in good lighting), but it just reads Patrick McMahon Cumbria. Look of the glasses matches with the handblown (slightly imperfect) Cumbria Crystal.
Any info would be great

Also if anyone has any estimate on price that would be amazing. I'm not planning on selling anyway because I love them, just more wanting to know whether I should consider using them or keep them safely displayed on a shelf.
Thanks everyone!
Steph
