Off the top of my head, Judge H. E. (Horace Ernest) Resley (1897-1991 I think) worked from sometime prior to 1947-sometime in the 1980s. All the references I have put him in Fort Stockton TX, but I think he was born in New Mexico. There was a bio published in Muzzle Blasts at some point. He is like an icon down in TX, the TMLRA even had (may still have) a match for folks shooting rifles with his barrels.
In his later years he was known to use Douglass and Numrich barrel blanks among others, but was also known to re-bore and rifle older barrels. He was known to lap the barrels before rifling, choking the last 6" or so at the muzzle. His rifled barrels were sometimes described as appearing a bit rough, but they shot well.
His rifles used a lot of original locks, various combinations of match sights and older style sights (or multiple sights to allow use in different matches). He made a variety of rifles. While the heavy bench rifles may have been otherwise, the "conventional" rifles I've seen/owned/used were rifled with a 1:48 twist, grooves typically .011-.015 deep depending on the barrel.
