I came across a Nixie clock made by European Electronic Counting. Apparently they were a UK company ? Clearly they had contracted or used an American made LSI IC (possibly be made by AMI), it is a unique looking ceramic IC.
So far this is the only example of this clock I have seen. The IC remains unidentified (I've checked it against a number of LSI clock IC's of the early 70's era, nothing matches), but also I cannot find any information on the company EEC.
Here is the clock & article:

Has anyone ever heard of EEC ? or can recognize the IC type ?
