Found this old razor handle. Got it identified I'm pretty sure but no idea on the key or the cap. Posted the key on an earlier post but someone asked about markings so here is the best I could do. Anyone seen this logo on the cap before?
The key may have been a re-make or duplicate for an automobile. I just found one similar to yours last week. Mine is the same size, shape and all, and it was marked GM. Yours looks to be about the right size for a standard ignition back in the '60's and '70's. Just a guess.
I agree with the key being from an old car. The cap might be from some type of water bottle. Interesting cap. Can’t wait for a positive ID. Nice finds.
