Very, very nice.

I, too, would prefer 'all original' but that's one mighty fine MS regardless.

It would be nice to have a 'pre war' MS chambered for a readily available cartridge. That's why I've long admired the M1924 (.30-'06).

Your 'M1908-.243' seems to be a very well engineered conversion, and guilt free (someone else did it). Sort of a 'best of both worlds' with low number, fitted case, original provenance, yet a near 'fresh' and proper modification.
