Much of what you ask for depends on what your price range is. T/C made both guns you are asking about. So does Pedersolli as well as many custom builders. Try to narrow down your request for better or more answers.Condition is just that, I leave nothing for chance. Look at the stock for cracks, the fit of the lock to the wood and barrel, the condition of the barrel and it's bore, etc. Of course when ever you buy a gun, you need and to me it is a must have. That is a range rod. Way too many people go and buy any gun and only have the rod with the gun to shoot and clean it with. The very day they buy it and run home with it to shoot it, they break the rod. Now they have a ball half way down the barrel or at least a dirty bore they have no way to clean it with. It is obviously great to have the range rod with you when you buy the gun, just to check the bore. In time, if you really are into muzzleloading, you will have a rod and jags for every length of barrel and cal./gauge out there.
