Ok?  Can you shoot the gun without it having any kind of malfunction or Ok from a parts purity point of view?  Reading Joe Farmer's book told me to expect all sorts of combinations of parts on rifles. Just a question.  Does it read 1896 or Model 1896 on 37247?

Still looking (sort of, but "records are made to be broken") for a higher "1896" than my 37045, but, so far so good.

37247 is not the lowest "Model 1896"; from other arms presented it appears that the change must have occurred around 37100, though I'd be surprised if it were a round number - to them they were just tools.
