I found these in my dad’s stuff and I’m not sure what they’re for. I’m guessing they’re for revolver work but if any of you know, please share. Thanks!
The one at the top is a bench block for pin removal and insertion. The middle is a tool to determine ejector rod "run out" (see if the ejector rod is bent or true). The lower appears to be a jig, but I'm not familiar with it or it's purpose.
