Hey Sacramento! Yes, an Eastern half-stock rifle would be just fine for TAPS. There were literally hundreds, if not more, of these fine rifles that made their way West. The Vincents were a family of gunsmiths plying their trade in the Ohio Valley during this period. And while they are most well-known for their smaller caliber half-stock "squirrel rifles", they did make a number of .50 caliber and larger rifles that went West during the migrations in the 1850's and beyond.
Great to hear from you, pard!
Regards,
Jake
