HEY POSSUM, can not tell its hard to make it out,
but check under the firing pin plate they may be a
letter on the under side of the plate.
IF you are not sure if a c/cylinder will fit your gun
send of your gun to taylers they will fit it to your
gun, thats what they told me a time ago, so i found a
gun shop what sold c/cylinders so i took my 58 with
me so i made sure of the fit, cost me a arm and a leg
but it was worth it lots of fun loading bp cases and smokless
thats COWBOY LOADS best of both worlds.
