Don't know if Ruger issued revisions for Blackhawk/Super Blackhawk manuals prior to 3/62 which is when mine shipped. Pm me if you have one in decent shape
I'm pulling from memory,, but I believe the 9/1/59 manual is the "multi-gun" manual used during that era. And if so,, there are actually 4 variations of that manual as well. You have to open the manual & look inside to see the different dates printed for the different ones, not just the cover date.
I'll look into it later.
I'm glad you brought this thread back up. I forgot to get into my manuals & double check my faded memory.
I was wrong. The 4 gun combined manual is cover dated March 31, 1957. It's the one with the different dates inside it. The next one is a 9/1/59,, and I think the next one will be 12/15/64.
