Winchester naturally experienced LOTS of place for parts for being stored for substantial time in advance of use. I have found several late production rifles that have a mix of barrel stamp models which means that Considerably more mature barrel ended up last but not least used and marked within the newer fashion popular at the time of assembly. and a pair of.
