It looks quite a bit bigger than a 19" to me. There were some large round tubes made, mostly used by DuMont. The 19AP4 does seem to get a bad rap. I wonder if other metal/glass crts are as troublesome. The issue is vacuum loss at the seam. If that were the case they all would be trouble.
I wonder why they ever made the metal tubes.
