Doug,
My opinion that the owner of a gun gets to decide what is done to it is well known. That said, I do report that my experience with a 218 Mashburn has been very disappointing. I bought a converted Keilerbusche(?) in the early 90s and using an honest chronograph, never could match the velocities reported for it. I now use it as a cast bullet rifle; it makes a pretty good turtle rifle at the hunting camp pond. Also, if you or your heirs decide to sell it, a "wildcat" will likely be harder to sell than a period cartridge, even an obsolete one. There are a couple Rook cartridges that 218 cases can be used as donor cases for and are pretty good cartridges, in the 25-20 class. It looks like it will be a great rifle, in the end. As I said, it is yours.

Doug,
If you can find the original barrel, the full serial number might be stamped on it ( the last two numbers should be 28).
Mike
