I Need a Picture Tube

I picked up the free Philco 2138 (1951) from the fellow in Larchmont, NY that was posted in the Swap forum. They were really nice guys, unfortunately, when loading the tv in my car he brushed up against the neck of the CRT and broke off the plastic cap! I thought that it would not be a problem to repair, but when I checked upon my arrival home the wires are broken off at the glass making reconnection impossible.
Now I've got the set, but I will not start restoration until I locate a tube.
Sooooooo....
I need a 20CP4 or any version for replacement, 20CP4A, 20CP4B etc.
If anyone has one sitting around it would be much appreciated.

BTW the set is in beautiful condition.
