Stamped Parts on Remington M1903s

What stamped parts would have been original on the following Remington M1903 production:
-July 1942
-August 1942
-October 1942
-December 1942
I know that several stamped components incl buttplate, butt swivel, lower band, lower band, trigger guard, and magazine followers entered the production stream at various points in later Remington M1903 production

As I recall, the stamped parts were not used to any great extent until @ September, 1942. For a while, both milled and stamped parts were used together in production - there was no "stop/start" date.
