Flat Top 44 Mag, Serial # 13xx, 1956 production. It was sent back to the factory to be refinished, NM 4 5/8" warning barrel, Super hammer, alloy ejector housing. It has the collared base pin but the owner did remove the transfer bar and put the old parts back. The man said he just can't handle it any longer. No it's not original but, at $425. it will make a nice shooter.
