New finds... information wanted

I've managed to pick up a pair of "Atomic Instrument Company" Model 1091's from Purdue yesterday. They were manufactured in 1962, and the reason that I claim that they're on-topic is because they 'count'. Googling for "Atomic Instrument Company" brings back a grand total of three results... nothing that looks useful. Does anyone know anything about the company or where a schematic could be found? These are the first things i've brought home that use a set of vacuum tubes (thermionic valves for those on the other side of the pond) to count. Really neat. I've put up a pair of blurry pictures of its front (I don't have access to good lighting at the moment...) on my web site: http://purdueriots.com/mr-atomic/ Warning: the pictures have a large resolution, but are only about 80kB in size.
