The M1 carbines sold through the DCM in 1963 were "unsurviceable-unclassified, safe to fire". Which meant they could be any condition, new, used, or re-built . They were not classified by condition. They were shipped with no magazine, sling, or oiler. But they were well worth the $20.00, including shipping, that they cost. About 300,00 were sold to N.R.A. members back then. All sales were recorded at R.I.A. and can be verivied through the CMP.
Are you sure that "All sales were recorded..and can be verified through the CMP" I have my Dads IBM AO I would like like to document.
I've read Orest Michaels comment that only about 5% of search requests for DCM sales requests result in a hit.
