This is frustrating as it's one of my best looking Elgins. Bright silverish case, clean face. The back is a screw-on and I can't get it to budge, so I can't determine what the movement grade is nor the case maker and info. I'll update this if I ever manage to do so.
Acquired: 2019
Circa: tbd
Current condition: does not run; can't get the back off
