Chris will be the one to ask for an real answer, but I am pretty sure that that information is available to nobody, at least not outside closed factory archives ... And if memory serves me, that info simply doesn't exist, other than line bore dates for the motor, which won't tell you when the bike was actually built or to whom it was shipped.
As a last resort, I guess I would look for the most recent "month/year" date code on any of the castings and that would at least tell you that the bike WASN'T built before that date. That is, if the most recent dated part on the bike has a casting date of August 1946, then the bike can't have been built before that date ... Unless, of course, its a replacement casting ... FYI, that "Aug 1946" date would be the "terminus post quem" for the construction of your bike ...
