The Ken Water's article is in my CD compilation. Nicely done, & always enjoy his work. The Griffin & Howe would be a nice piece for sure, as well as the Ballard. Not certain as I'm no Ballard sage, but if no cracks were evident on the reciever I believe it could handle the Lovell Ok, and itself would be a lovely piece. Wish I could pick up a bundle of Martinis for that price again. They used to be "club guns" but were extremely tough and well made.
Should start another thread on this but if you like wildcat Martinis, I've included a couple of pics of a large frame I have in a wildcat 577/450. The shoulder of the Martini Henry 577/450 was moved forward so only 1/2" of neck is left & holds 170 grains of Fg or FFg. Still trying to confirm if it is the work of Ellwood Epps who was known to have worked some with the round.
Above are 2 of the wilcat 577/450's on each side of the 22 short, along with some 577 Sniders, 2 regular 577/450's and a 303 British.
