Strange marks on a Scottish Dux medal

Hello all,

I have just started collecting silver after buying two pieces from an estate sale.

The first is an 1860 silver military prize cup for shooting and the second is a Dux medal with 1896 on it.

My question is, can anyone tell me the assay town mark on this medal? I can’t find it anywhere! Also the makers mark and date letter would be apprechiated

It’s a Glasgow assay mark. Y is 1895 and JM is James Marr (or Mark) of Greenock.

Superb! Thanks for your reply 8)
