I would offer the opinion that the No.3 was a .375 Winchester and not a .375 H&H, unless it was aftermarket rechambered. Also, the 1V in .300 WM was a cataloged offering from about 1972 for about 6 years. they are not often found today and could be considered rare, especially the Liberty marked one.
There are a lot of No.1's rarer than this one!
I'm with ENU, I've never seen, nor heard of a No.3 in .375H&H. It's not listed in Claytons' book or Chad Hiddleson's book either. If one was produced, it would be a find of significant porportions.
I've thinned out my No.1s and sold all my No.3s, including a NIB .30-40Krag, Liberty.
I'm down to just a few No.1s, but I still do have a 1V in .300WinMag, Liberty, along with a 1V in .25-06, Liberty. I also have three non-prefix rifles and a 1S in .300 H&H.
There is a considerable storehouse of knowledge on the Ruger-1 forum. You guys ought to stop by and visit with us.
