FYI - The early versions of both the T/C Hawken & the T/C Seneca were unmarked (barrel roll-stamping) as to which model they were, so the best way to determine exactly what rifle's on hand would be to measure the rifle.
T/C Hawken's were made in .45, .50 & .54 caliber, all had 28" barrels (measured from the muzzle to the forward end of the patent breech - look for the joint just ahead of the ignition) that measure either 15/16" or 1" across-the-flats.
Hawken's had heavy barrels, full-size locks & full-sized stocks that look identical to Seneca parts, but will measure differently, and are not interchangeable.
Some Hawken parts are available from T/C & aftermarket vendors.
T/C Seneca's were made (only) in .32, .36, & .45 caliber, all with 27" barrels that measure 13/16" across-the-flats.
Seneca's had lighter/slimmer barrels & smaller/slimmer locks & stocks (compared to a Hawken model).
Almost no Seneca parts are available, since the separate T/C buildings that made the guns (Cherokee, Partiot, Seneca) burnt to the ground, leaving no parts, design plans, or special machinery use for those downsized guns.
Below are my two Seneca rifles (a .36 & a .45)


I hope everybody had a safe & happy 4th of July ! .
