Arran - RCA produced the tuning eye tubes, and promoted the heck out of them.

There is no doubt that Philco knew how to pinch pennies wherever it could. You can thank Jim Skinner for that.

Brand Z also used shadowmeters in the early 1930s as did a few others, including Atwater Kent, I believe. I find it interesting that Zenith came out with "Target Tuning" for the 1937 season which, if I'm not mistaken, was a variation of a shadowmeter? And then for the 1938 season, they used the 6T5 eye tube made by Sylvania to Brand Z's specs. I am sure the 6T5 was an expensive endeavor which is why they ultimately switched to the standardized 6U5.
