Hey Muffer,I have just been told about a 29 dated receiver with a 39 barrel.... here is his description.... Is it possible?

I just bought a Lithgow all matching, everything is MA 39 or some stock parts are 1940, in Queensland Maple and Coachwood.... all flipping matching all Australianicon. The Barrel date is 12-39 and the blue on the main parts of the rifle is near 95% (not a reblue I have been collecting for many years now and the stampings are fresh and not rounded, correct and real blue........the bore is smokey but strong lands and groves (probable some neglect after it got to the US... lots of folks over here are clueless about corrosive priming. any way here is the kicker that has me lost. The receiver date is 1929! not 1939! When lithgow was gearing up for WWII did they use old receivers. The bolt matchec and the bolt head is dated MA39.... what is going on? Thanks for any replys.
