A friend of mine bought a Marlin .50 caliber muzzleloader that looks about 95% T/C Black Diamond. From what I can find out, it was made by T/C for Marlin. It is configured as a #11 ignition system. My questions are does it use the same takedown tool as the Black Diamond and can it be upgraded to 209 ignition with the kit for the Black Diamond? Thanks in advance.
