If you are asking if one tube can be replaced, the answer is yes and the cost will far exceed the value of the gun. It would be much easier/cheaper to have a gunsmith fit replacement barrels which occasionally appear on e-bay. I recognize that if this is a family treasure, cost doesn't matter and if still interested send me an e-mail, let me know where you are, and I'll give you some names.
