Sticking my nose where it does not belong, I would say yes. You can get a Model 7 with a 6 grind, so I would say you could get a Model 3. BUT I have been wrong, but not for the last 3 minutes.

After using Mitchell's search "tool" he talked about for this forum, I was wrong, wrong, wrong. Here is an answer the Capt stated a few years ago, with someone asking about a Model 3 with a 6 grind.

Mike,
Yes I have. Although they are not available at the present time, the Randall shop made them in the past. I don't know the exact amount, but it was certainly more than just one forging and went on for a period of time.
Best, Capt. Chris
