Springfield Trapdoor Bannerman Special - Might be a Shooter

[m1903rifle]

No such thing as a M1878 Trapdoor. The block is actually marked 1873 ..... the later M73 blocks were interchangeable with the M84 blocks, and were installed until they ran out of them. The receiver is actually a M84 receiver. The rear sight appears to be a M1879 Carbine sight ( marked with a "C" on the side ).
