Do You have a user manual ?

All I have is the 1955-1966 Field Service Guide. That covers the CTC-2 through CTC-20 service info. But there’s not really any model number-dating info in it. I'm assuming most 11's were made in 1961, but I'm not sure. Possibly the serial numbers have encrypted date code, but I've never heard of anyone explaining the numbering system.
