Always nice to find a restorable "T" If you decide to repair the missing sight "ears" I've got a few junk Savage actions and I could zip-disk you off a pair. Since the finish is so nice on your receiver, a discreet silver solder job might be best, though the heat will affect that somewhat.

Pity about the butt, does it have the "S51" stamp on the underside and/or the rifle serial number of the rifle on the "tongue" (the part that goes into the butt socket on the receiver)?

I expect B.D.L. Ltd. could find you the right butt and cheekrest; the original would have been beech, only the Canadianicon cheekrests were walnut.
