I picked up a another Ballard on GB couple months ago, Merwin and Bray (from researching Dutchers book a late Ball and Williams) in a 32 RF. I was a little disappointed when I first got it, I was thinking it was going to be a later model that could shoot rim or center fire, teach me to do my homework...
Anyway, after getting it and finding out the truth, I let it sit for a month and gave it some thought. I didn't want to alter or butcher a piece of history but I have to be able to shoot a firearm or it's not staying in my collection.
I cast the chamber and it was beyond hope (.010" out of round), scoping the barrel it had three rings and several bulges in what was left of the rifling. The wood was good to better in fit and finish. My decision then was to bore the chamber to the .32 rim diameter and .200 longer, make a plug to fit the original .32 extractor and over bored chamber, then drill this and the barrel and install a .22RF liner. Finished this the other evening, made a new manual extractor and even before I had the extractor installed had to take it shooting... What a trip.
Don't have any plans of refinishing wood or metal, the only alterations I did outside of the bore - I chose to cut a dovetail in the action, rear of the hammer as seen in many of the rifles of this vintage for a sight. I may post pictures later of this and the sight I made, after the coloring...
Shot it today - very pleased! experimenting with ammo, it likes Norma Match - if I do my part it's consistently smaller than 1.5" - five shot groups -100 yds. benched... Gotta love those Ballards!
