I found this at an old 1920s home today after a random door knock paid off. :yes: I also found a solid brass belt buckle as well. Thanks for looking. Any help on IDing the age of the spark plug would be helpful. THANKS!
That buckle looks like the one I wore with my Boy Scout uniform in the 70's. It would hold my citizenship awards on it (I think that's what they were called). A BSA buckle would have an emblem on it though.
