I've owned Whites since the early 90's, followed them a year or two before that, and currently own three. Here are some of the names that White Rifles has been manufactured under at one time or another, in no particular order, but I'll try my best from memory to keep them in order. I might even forget one, or two, but I doubt it? LOL
Doc White was the man that started it all, and even though he did not always own the Companies, he was usually involved in the design of the rifles. He was involved in some capacity, right up until the very end. If there is an end? He still puts together some custom rifles, from parts and pieces he has acquired over the years. I don't think it ever ends.
This below is not historically correct, just pulled from my best memory, and I have CRS if that tells you anything. So don't crucify me if I have something out of order, wrong company names, or the wrong years next to ownership. This is my best recollection of how things went down. If I get anything wrong, please speak up and point it out.

Hundreds of different custom builds from Doc over the years.
I know I am forgetting at least one other odd-ball model of inline, but can't remember it right now. There were also some sidelock Sporting Rifles over the years too. Doc built a few rifles in .367 caliber for the White Shooting Team, and won the Nationals in 2006. I think it was his last ditch effort to secure a buyer, but so far there have been no takers.
I have owned a White since about 94-95, but not until I drooled over them for a few years, and picked up a couple more along the way.
That might be a bit more than you asked for, but it was a fun ride while it lasted.
I forgot the Alpha, the one they never built.
