"A" on Winchester Stock

[boykin]

A friend has an early Type 1 Winchester. On the bottom of the pistol grip is a small capitol "A". No rebuild marks and carbine is all correct high wood. Anyone know what this means, I have never seen this before. Thanks to all.

If there is no proof P on the underside of the grip then it's most likely been sanded off. The A could be for anything but not factory done. How does the acceptance stamp look if it's still there?
