Can anyone help me find a date for this ring.

I inherited this ring when my grandfather died and I am trying to work out who it could have belonged to.
I can read the other markings but can’t work out what year the “Z” is from.

Welcome Amylee. Your album is set on private, so no one can see your photos. It is best to post them directly in this thread, here is info on how to upload pictures, please remember to click on 'full image' when you post:

Looks like it is Birmingham, and the Z from 1974.
