6.5mm Carcano M91TS Moschetto per Truppe Speciali (Special Troops carbine).
Made 1916 Stamped BRESCIA Matching stock and barrel/receiver. AC8758
I don't know a lot about the gun. Appears to be in good shape. It
is missing a cleaning rod and the screw that holds the metal piece that
wraps over the stock at the front of the gun. The stock seems to be in
EXCELLENT condition, I have no idea if it was refinished.
