Found this really old locke unipart the other day. Forgot my camera, so i only have a picture of it after i found it. Wasn't much to look at when i found it, this is it's good side. The insulator is embossed with around 8 patent dates arranged in 4 rows, 2 dates per row. Pretty cool, there is a lot of newer JD chocolare brown things out there (wich would be nice if they werent all smashed) so this was a little misplaced among them.
