Any member knows where I can find a correct SC 1903A3 serial number/production month table (preferably online)? I am checking a rifle with s/n 4748XXX. I did online research but got conflicting info. For example, according to National Park Service and Oldguns.net, this rifle was made in 1944, while the Month-end serial number table complied by William Hansen showed it was made in Sep 1943. I am very confused which one is correct.

The barrel on the rifle was labeled as SC 7-43, is it period correct?

Thanks.
