Hello, and welcome to AK!
There is no direct sub for the 21EP4 unfortunantly. I have a Philco that uses that tube. It has a barrel shaped screen that is more or less flat in the vertical plane, like the Sony Trinitron, most other CRTs had a spherical screen. there might be an electrical sub but it probably won't fit the sets masking.
A 21" Bakelite set is pretty unusual, any chance you could post o picture of it?
