Questions- Chrome plated M1A1 carbine
Chrome plated M1A1 carbine- Stock cartouche postwar refurb by Augusta Arsenal (AAM).
Underwood receiver (ser # 2,844,XXX).
I believe that its an original mixmaster w/ bayonet lug and adjustable rear sight.
Came w/ one chrome USGI 15rd mag and one chrome USGI 30rd mag.
All parts chromed except springs and slide stop (park?).
Sharp rifling in barrel/ no pits etc. Unsure if interior of barrel is chromed.
Gas piston seized up- does not move. Used Kriol oil etc. Have not disassembled.
Other then that, all parts work.
Have not/ do not intend of firing.
I've done my homework as best I can- all parts markings are USGI. Stock/ folding buttplate all cartouched/ marked correctly.
No provenance.
Questions- any help appreciated.
1- Does chrome plating increase or decrease value?
2- There is a plus or minus 1/4 inch "M" on left side of pistol grip. Have not seen any explanation in my searches. --Does anyone know what it means?--
Thanks,
