Tentman,
I won't say I've never been wrong,because I have often been.That said,it is still my opinion that most,if not all,so called "factory" mounted scopes were actually farmed out to local gunsmiths,photos not withstanding.This applies to other manufactures as well.They didn't want to slow the production lines down for "one off" scope mounting.As a service to their customers,they would take a rifle in and have someone else mount the scope. This type work was a big part of my gunsmith buddy's business.This applied to other special work as well,such as sideplates on Ruger #1s,etc.I would be especially interested in seeing Kudaue's opinion on this.
