But in my opinion, it's highly doubtful that your stock is original to the receiver.
I have attached two generic photos I had on file. One photo shows the earlier butt splice that goes through the rear sling swivel, the other shows the angled splice change made very early in '43. Check your inspection stamps on lower butt stock. Stamp closest to tang should be the "Na" (Nagoya), with the "ri" (toriimatsu factory stamp) further back.
