I am in need of some assistance with my model 41...have pristine early 70's 7 3/8 with serial# matching box etc...unfortunately it is missing the 7 3/8 barrel. Got it from a relative's estate. I do have the 5 1/2 barrel but missing the rear sight.

They seem impossible to find...I have been searching all of the notable ke sites. Any assistance would be appreciated.

Thanks!
