A very nice looking set. I especially like how the front mask cleaned up and that the gold lettering is looking so good. Good work!
You may want to check out the Antique Radio Forum (if you are not already a member) and post a request for a CRT. You just may find one eventually. Sad that so many of these older sets and CRTs were taken to the dump.

Note: The ARF site is going down for maintenance this week coming and will probably be down for a week. So don't be disappointed if it doesn't work right a way...
