Need ID help with missing rear sight

[jvg5576]

I recently picked up a old Western Field Model 31 that has a base for a peep/target sight (see picture). Since I went through the trouble of making a new firing pin and the rifling is in great condition, I figure I might as well fix this too.

I've searched but the only sight I can find that even comes close is the Lyman 90 MJT.

Any ideas on manufacturer or where I can find replacement parts?

Thanks LUCKYDAWG13. Numrich was no help but I found a lot of useful info on rimfirecentral. Unfortunately, this mount didn't look like any of the pictures I found.

I'm going to try Dick Williams next.

The Western Field Model 31 is a Savage 620. ( according to Numrich cross reference) It looks like you already have part of the base for the peep sight. I thought most all .22 rifles of that era used a common bolt spacing and mounting for the rear peep sight.

I've discovered that cross reference to Savage 620 in several places, but that's a shotgun. The Western Field Model 31 22LR was a Mossberg Model R made for Montgomery Wards, as far as I can tell. At least the firing pin is the same.

You may be correct about the common bolt spacing. The spacing is 0.313" on this one and the slot is 3/8" wide.
