The miniature tubes were introduced in 1940, I did not know that. What company (or companies) first produced or designed them? If I was an RCA engineer, using upcoming smaller (and lower-priced?) tubes would be an excellent plan for a more-affordable TV set. This all may have been hashed out in the past, but speculation is still fun. Are there ANY 630s with the script-type decal known?
