I would suggest you think long and hard about re-proof of the guns in England. The proof house is doing a great job of blowing up perfectly good old English guns, due to a change that requires re-proof with two rounds in each barrel, one generating proof pressure in the chamber, and a second round generating proof pressure 9" down the barrels.
Cogswell and Harrison "Avant Tout" models have made a recent name for failing English reproof, others have as well. The cost and logistics of getting them back and forth is problematic, as well.
I'd turn them both over to Kirk Merrington, and take his advice about what both guns need to continue shooting. I'd also feed both of them the ammunition they were originally designed for.
Good Luck.
Best,
Ted
