Long Branch - Linking Serial Numbers to Month of Production

[CODFan]

I thought I would try to match-up some of the rifles I have to the list:

1941 - 0L32xx and 0L39xx ('41 dated barrel and rifle with early features) = Nov 1941
1942 - 2L61xx ('42 barrel Numbered to rifle round cocking piece) = March 1942
1943 - 50L29xx ('43 barrel) = October 1943
1944 - 64L66xx ('43 dated barrel) = April 1944

So my observation is that the list does seem to be in the range.

For the '44 dated receiver and '43 barrel .... barrel production at full capacity ahead of receiver production/dating? plausible?
