What you have there is probably the EIA manufacturer code. I have no idea who made that TV or the CRT you are trying to fix, but, over on AK is a list of them, courtesy of another member. Lotsa luck...

Edit: Never mind, the list is from 1958, and stops before 1100. Chances are you couldcontact the EIA and ask them, perhaps.
The sad fact in play is many collectors don't consider these collectible, and walk right past them at the thrift store. Depends on one's taste. I have to balance my junkin' junkets with an occasional piece of Corning Ware or a bath towel to keep my better half pleased. If it ain't round, it better be tubed, or it won't be comin' home with me. Again, good luck on your quest.
