one US world war two M-1 M-2 carbine parts,unfinished redstone arsenal triggerguard or trigger housing,new old stock (NOS) these came from the redstone arsenal and the are unfinished,they have no markings that I could find,I suspect these were an under the table contract from the vietnam era,probably for cambodia,laos,or even south vietnam,the last nine left have some surface rust,can easily be cleaned off and or polished,since these are unfinished.
