Shooter,
So is doesn't have a "snap on" case back? If so, use a DULL knife blade?? (Underside, at either end, between the lugs, should be 1+ tab/s, for blade leverage? (Then perhaps get a "case back opener??")
And that looks to be about a 22- 25mm square, molded glass (or acrylic?) crystal??? Likely listed in the 1960 G-S, or 57- 59 BB, Perfit, SUC, etc. catalog/s???
Best :-) Scott
