I concur completely .... now !
I sinned years ago , I cut down 11 Trapdoor Springfield's for " Geronimo an American Legend "
They were not pristine guns to start with , but we needed Carbines and a hero piece for the film.
I also cut 4 Uberti 1860's for "Avenging Angel" another TNT movie .
I recall I did some guns for the North & South trilogy, all were within may Prop Makers profession
and cut a good number Replica Muskets to carbine length for reenactors...
