I have a finger-grooved stock with several inspection marks, some seem unusual. I welcome any comments or explanations.

On the left wrist is J.F.C. in a box with a boxed R.A.-P slightly overlapping.
behind the rear sling swivel and forward of the trigger guard there are five point stars. On the lower wrist behind the trigger guard is a 7, and a P in a circle.

On the tip of the stock is a small S.in the cutoff recess is an E and possibly a Roman Numeral 5.

Inside the hand guard, there is an R at the rear sight end, and an N near the center. Inside the stock is an R forward on the magazine area, and some unidentifiable mark forward on the receiver area.

I'm aware that the JFC is Coyle at Springfield 1904-1918, and R.A.-P. is Raritan Arsenal post-WWII inspection. S on the tip probably indicates Springfield.

Mainly, I'm interested in finding out what the significance is of the two stars, the R inside the stock and hand guard, and the E in the cutoff area. --TIA
