I got another old die last week. A unused working die.. Nice Art Deco ish design...
The 3 holes on the cartouche could be used for like some of our glass panel rings with emblem and the 2 screws from behind to affix, or maybe even to solder a panel on..
Seller calls me when ever he finds dies that are European or European made sent here. He had found a bunch of old [1950s] NOS working dies.. this was the only mans ring..
Serial numbered,,and depression [red] is for when in holding chock there was another holding screw/bolt.
- Most are in cardboard or wood boxes which he throws away after unpacking/inspecting
... I told him I'd give him a bit more from now on IF he saves the container!!!!
