Hmm. That's a good question. I don't think Ruger shipped consecutive serials and they're not doing letters. Probably no way to tell for certain. I'll have to see what I can dig up.
I would think that the frames would have been made with consecutive serials, even if they weren't built into complete guns or shipped consecutively. It would be too much of a hassle not to. Hopefully you can convince them to send you an email saying if it were made before this date in 1964.
