Proof marks on a P14

So I have a Remington (RE *) 1917 built P14.
Its got that many marks on the receiver they ended up putting the Proof stamps on the muzzle end!

I know what a few of the marks mean but if someone can identify them all that would be awesome. I have probably mentioned it before but it has another serial type number on the right hand ear ( this was normally only done to rifles that would be scoped, and ONLY ever done to Winchesters of course)

Of most interest to me is what the CVA means on the right of the first pic and what the stamp in the left top of the picture with the C in it means, of course the ear stamp is a curious factor as well and doesnt look to be done at the build time but later at an armory?

The military proof mark is sideways in the lower left of the first pic. It’s a crown above GR then crossed flags and a P. It has A BNP proof at 90 degrees obliterating the P. The BNP and other muzzle end markings were added when it was sold out of service. They were not standard military proof requirements. The marks just left of the RE might be a very faint inspectors mark. That would normally be a crown with a number under and a letter under that.

The Arrow with a dot under is the British acceptance mark.

Actually, I think your CVA is the inspectors stamp. It’s half a crown, with something else under, and the A under that, parts lost in the curvature of the receiver.

Remington made P14's are generally poorly struck when it comes to proof marks etc. I think you'll find that CVA is actually part of a crown at the top (poorly struck so looks like a C), then other parts of the inspectors marks. Will check my remington P14's to confirm.

So from what @mimms2 provided this could have been SoS from 1954 onwards ( the crown and BNP at the muzzle)
