Came across a old post on another forum from mid 2012 where a member inquired about a NPM he got from his Father.
NPM 5,260,783 with Marlin barrel. Stock SA, Internals typical Rebuild parts/mixer.
Another Mis-stamp?
Instead of a 5...... If the first number was a 4, It would fall in to a NPM serial Block.. IIRC
Thoughts?
