Ok. I went on the eBay hunt and got four, I believe 2 are Disston keyhole saws? not sure about other two?, for $15! Which I thought was a nice buy.
I’m excited to get them in the mail and clean them up. I’ve put the eBay picture below. I’ll try to post more when they arrive and I’ll also try to put before and after pictures in the ‘Hand Tool Before and After’ section. Thanks for the help and suggestions.
