We used more Westinghouse tubes than any other brand. It was our primary brand throughout most of the 70's, all of the 80's and into the mid 90's when we closed the storefront. I figure we went through several thousand. I believe the name was actually licensed to a tube house at that time rather than being actual Westinghouse products. We used them because of all the tubes with name recognition they had the best price and we got good performance from them. I think Westinghouse quit making tubes and just licensed their name about the time the 'Reliatron' slogan was dropped. Of course, they continued to say, "You Can Be Sure If Its Westinghouse". And they were good. We had very few problems and when we did, it was replaced immediately without question within the warranty period.

Their EIA/RETMA code was 337 and they used it on every tube even if the tube was made by someone else or even made in Japan. Many of their USA tubes were made by GE, the frosted writing and dots being the giveaway. Tube writing was almost always yellow and date codes were year-week. Some times the date code would be missing, but it was usually there.
There were a couple of small variations on the box style on your right, but not enough to scan separate pictures. One variation was a slight different top tab and the other was small variations in the shade of blue of the box.
The box on your left was the open top and bottom type that used a corrugated insert to hold the tube.
