Not sure of the provenance on these, were gifted to me years ago.
Barrel is a GI replacement black oxide (?) finish,. Leg marked MP on left side with #73677 on right side. Top of hood says 45 Auto and beneath is #7791173. Some wear marks on finish like it has been on a pistol. Bore is shiny and does not appear to have been used much. Link and pin are present.
Bushing looks new and is not fitted to the barrel, barrel opening is too small to admit barrel. Stamped NM on front.
Cant post pics but can send from my phone.
Price $50 shipped and insured in a SFRB, payment check, MO, PAYPAL (F&F or add 4%).
