If you can get tube shield bases from a junk 1937 Philco set, they use the square shields but the bases are four flat "fingers" that will allow the use of metal, GT or ST tubes.
Just a thought.
Codefox has a good idea regarding the metal tubes, but bear in mind that if you go all metal with no shields, any future replacements will also have to be metal. When pin 1 is grounded, the metal shell serves as the shield.
