Bob, somewhere I've run across that name before in another ad, but I can't remember where. When I find it I'll post it.

Many of the ads from the late 40's-early 50's were for CRT makers, so I know many of them were supplying OEM set makers too. It's like any business, when it first starts out there's lots of competitors and people trying to get in the game. After a few years they dwindle down considerably.
