M1 Carbine stocks - Arsenal box of ten, still filled with five

[Promo]

Couldn't pass on this kind of time capsule - an original paperboard box from the Red River Army Depot. Not sure if the BR4 A/A 9/76 on the outside would date the box to September 1976, but at least a wrapping paper on the inside clearly has mentioned "AUGUST 1967" on it; that though possibly refers as to when the specifications for that paper were made.


It contained only five of the original 10 stocks that were in. Interestingly all five were re-milled to M2 configuration, and this in fact quite rough. Also the seem to have been kind of overhauled (possibly during M2 re-mill?) and mixture of about everything regarding stamps. They are in desperate need of oil prior to being re-used, and aside of the recoil lug (possibly needed as locking position when re-milled to M2?) all metal parts were removed.


Attached are pictures of the box as well as the five stocks that were in. Maybe someone else can tell me more on them. Among all five stocks only the first one was an I cut (and therefore pictured too).
