26mm Kollmorgen Scope in 1" Weaver rings?

I have a 1955 Marlin 336 that I want to set up with a period scope and mounts.

I found a set of the old steel weaver bases and the old rings with the screws on one side only.

I tried a Weaver K2.5 but the setup deosn't allow that long scope forward enough to get sufficient eye relief.

I have a 26mm Kollmorgen 2.5 and have managed to get it mounted, it gives proper eye relief.

Obviously the rings will not close up as much as on a 1" scope but i have the screws in 5-6 threads. Forsee any problems?

You could just buy 26mm rings.

If you tightened them as much as you could by hand with a fitting screwdriver, and they did not strip, they should hold.

The old Weavers are about the only ring you can do this with, it should be fine.

Thanks, it's only a 30-30.

Did Weaver even make 26mm rings back then?

Almost all scope rings that have a 2/3 - 1/3 split will work on both 1" and 26 mm tubes. Rings split in halves (most American makers)won't work. If you look at EAW and other European makers that have unevenly split rings, the part number for 1" and 26 mm are usually same. That's why the Weavers work.

If my memory isn't playing tricks on me, there is slightly less than 1 m/m difference between 1" and 26 m/m diameters. As such, it should not be very difficult to lap many makes of 1" rings to 26 m/m capacity.
