Recently picked up an early 50's 99 that was drilled at the factory and came with a classic Weaver 4x in a Weaver tipoff mount. It is a Christmas present for a grandson, and as it is very accurate, will leave it as purchased for the time being.
Imagine your grave on a windy winter night. You've been dead for 70 years. It's been 50 since a visitor last paused at your tombstone..... Now explain why you're in a pissy mood today.
