Mr. Moody favored using 12L14 for his barrels, didn't he?
Twenty or more years ago I corresponded with a gentleman named Robert Wyant, of Huntington, WV, about the Billinghurst-pattern target rifles he built using Moody barrels with false muzzles. I never did put together a Billinghurst, but Mr. Wyant sent me a tracing of his stock pattern that I still have.
