Lee,
They are for the older long-tubed target (Unertl, etc.) scopes, and as you say, for the 7+" spacing.
If you haven't seen them before, they must be rare.

I knew they were out there somewhere. I once owned/bought an early 1971 25-06 "V" that had these bases and a Redfield 3200 scope.
That being said I have nevr run across a set with the packaging for the "V" and the long scope configuration.
I find the Redfield bases for the "B" sometimes and often use them and have a set in the package for the #3 and short spacing but haven't run across these seperate in the packaging.
I would class them as rare but it's a pretty narrow market!! ;-)
I may give them a try on the 1V 243 I picked up this winter.
Ross- most No. 1 related stuff occupies a narrow market, and the growth potential seems pretty limited. Even so, I'd guess these Redfield bases "should" be easier to find than the original Ruger bases, and would be sought after by anyone with an older 1V and no bases.
I wonder how many are sitting in drawers or got thrown out over the years by surviving family members who had no idea what they were.
Lance
Lance: I rthink this base has always been uncommon/rare. Redfield had the base for the "B" designed and on the market withing two years of the #1 being introduced. Same thing with the #3.
I suspect that with the introduction of the 22-250 "V" in 1970 and then the 25-06 in 1971 using the wide hole spacing and the older long tube scopes, Unertl, Redfield, Lyman etc they may not have seen the market as being that big. Framkly I was surprised they made them at all and they probably were discontinued in about 1975 when the factory started adding the third (short) set of holes on the "V".
I bought a few Redfields for the "B" over the years as I needed them and ran across them. Finally found a source on Auction Arms and bought a set. The he advertised another set. I e-mailed him and bought all six sets he had NIB. I think I now have a lifetime supply on hand.
I guess I'm going to have to look for a set of these and mount up the old 3200 Redfield on my 1972 25-06 "V".
The long ones are awkward from anything other than the bench and a real pain in the bum if your dragging it in and out of the pickup to shoot squirrels or coyotes. BUT they certainly look "cool".
If you run across another set, keep me in mind
We won't even talk about the factory original Ruger version. ;-)
Ross,
If I do see another set, I'll let you know. I bought these just because I had never seen any, and I'm a bit of a sight/scope mount junkie, especially when it comes to No. 1 stuff.
I still have a NIB set of the Redfield bases for a 1B/S in case I ever need them. I had a set on a 270 that I sold a few years ago. They work well, they're just not as elegant as the quarter-rib (or Buehler or Conetrol for that matter).
Lance
Lance: I mostly use them when I run into windage issues with really big scopes, 8-32X and a Leupold 36X boosted to 48. There is so little adjustment internally in the scopes that it's often hard to get the windage right with the non adjustable/shimmed Ruger rings.
The Conectrols and Buehlers do offer coarse windage adjustments but require their rings.
The thing with the Redfields id you can use, Redfield, Burris, Leupold or most other major manufacture rings.
I startered useing them years ago.
The other application is with the 8x-56 Weaver that I run on several "coyote" specific #1s. The Redfield bases and a medium Redfield ring puts the forward objective of the scope right at the thickness of 2 playing cards off the barrel That's as close as I feel comfortable setting and eye position isn't totally out of whack.
Also interesting is the "V" packaging. The "B" and #3 bases come in nifty little red Redfield boxes. ;-)
