In my experience most shooters are more interested in an accurate rifle with a perfect barrel than in one that is early, or all correct. An all correct 1941 rifle would probably have more appeal to a collector, who would most likely prefer correct worn parts rather than incorrect parts in perfect condition. A '41 barrel in mint condition might come along someday, but maybe not, so if you want to finish your restoration, you could install the worn barrel now and keep looking for a better one to put on later. Most people I know already have thier favorite accurate rifle, and would only buy an early correct rifle because it is what it is, an early correct rifle.
