Michael MichalskiFOUND Wanted to Buy Vintage Scope for SA 22
Sambarman338 has a Nickel scope for me in Australia and that is my backup position. However it would be a lot less hassle if I could find a period correct one here in the USA. Anyone know of one in decent shape/price for sale?

sambarman338Good thinking, Michael. That scope is still wrapped to go but I think you should look for something short with a 7/8th or 3/4-inch tube.
Almost everyone made models for .22RFs with those narrow tubes but I'd look for something about 2.5x that was thought strong enough for centrefires.
The Pecar PK-3 (3x) or IS (2.75x), pre-war Zeiss or Hensoldt Zielklein (2.25/2.75x), Kaps Zieljagd 'A' 2.5x, Stith Bear Cub (2.5x or 2.75x?), various pre-'64 Leupolds or a Lyman Alaskan (2.5×) would be high on my list - but something with image-movement from Redfield, Weaver or Bushnell would be easier to mount.
A 4x scope would be better for more-distant bunnies, of course, but I don't see the little Browning as a sniper's rifle ☺

StonecreekWould a Pecar 2.75 x 64 be of interest to you? 22mm (7/8") straight tube (no objective bell) with post/crosshair in very nice condition. If so drop me a PM and we'll discuss.

sambarman338If still clear, that Pecar would be just the shot.
I've got a very early one with two screw-stopped turrets - but mine is just a curiosity, being compromised optically.

Michael MichalskiHave a Pecar 2 3/4 X 60 on the way. I think the 60 is the tube diameter and wonder what that is in inches

eagle27Pecar designated a 'luminosity factor' in their scope monikers, the calculation being the square of the sum of the objective lens in mm divided by the scope power; hence their 4x36 scope was called a 4x81 and their 2.75x22 scope called a 2.75x64.
The luminosity was supposedly a measure of how good the scope was in poor light.

Michael MichalskiThanks eagle27, interesting. Mike

Yes, Eagle, and that 'relative luminosity' is truly relative because it assumes we have square scope lenses and square eye pupils. A better idea of light transmission might come from reducing the relative luminosity by 21.5%, which gives something close to the area of a circle in square millimetres.
Better still, just quote the exit-pupil diameter and, when buying, compare it with the shooter's eye-pupil potential: old eyes are unlikely to benefit from more than six-or-seven millimetres but young miopes might use up to nine. Big exit pupils can give more-flexible 'eye boxes', of course.
PS: glad to hear you found a scope, Michael. I'll put the Nickel back in the wooden box.
