Sometimes I wonder the value of sweating over serial numbers. Sometimes the right parts are good enough unless its a real special specimen. That 99R looks like a solid rifle to me and far from a parts gun.
If it was a vaunted Winchester model 70, no collector would care if the stock had been replaced, if it was still correct in configuration.
It is interesting that the Model 54 isn't nearly as valued as the Model 70 even though it was the same rifle sans extraction on bolt and floor plate release to unload.
And another mystery is, there is not nearly as many 54's as 70's. Grandfathers to fathers regarding design!
