Also, just because the rifle is sold to a collector as "unissued" doesn't mean it stays in that condition. Many guys don't think twice about being the first one to shoot a rifle in that condition, and some don't think twice about taking the hack saw to the barrel, and the wood saw to the stock.
It is actually a curse to have both a conscience and unnissued rifles. They tend to collect dust. You can't even clean them!
I have a (likely) unnissued 1945 Cno7 cadet .22 trainer in the grease. The tag is on the chest from 1948 when it was put in to long term preservation. The sling is in a wrapper, and (strangely) it also has an action cover wrapped in there too. I say strangely because the action cover does not show on the checklist (also in the crate).
I got it in a 3 way deal....the guy first in line was going to use it as a shooter. (right Craig?)
