These are 1940s Sylvania, not '50s. Per reports directly from a few audiophiles, quality on par with Tung-Sol 6SN7 round black plate.
Note: I never heard Tung-Sol 6SN7 round black plate myself.
Follow Ups:
I have some from the late 40s. They are Ok, but not great. Comparisons are irrelevant. I gather you are trying to sell some.
If so, don't use the Tungsol comparison.

I'm in agreement with Len. All of the flat plate Syls I have are from 1951. One plate is slightly in front of the other. Unlike Ken-Rad, they are mounted straight on the mica, rather than on a diagonal (reminiscent of RCA). There were both a black plate and a gray plate version made in 1951 that have very different sounds. The gray plate has a lush midrange, but lacks fine detail. The black plate has plenty of detail, but can sound a bit harsh. Neither of them has anywhere near the finesse of the Tung Sol RP.
What are the date codes? In retrospect, it's possible I saw a few from 1949 (have gone through too many tubes to have a clear recollection). I have never seen any staggered Sylvanias from early to mid 1940s.
Yes, they are from 1949 to 1951.A mediocre 6SN7 at best. Flat and one-dimensional. Not terribly musical.
