Pancake is what the design is called. The tuning shaft is offset as opposed to planetary tuners which are straight. They were made by numerous companies, Waverly, Elton, Schaller, and Grover, to name a few. Most Gibson RB100's had this style tuners made by Elton and no small number of Vegas from the 1950's and '60's had the same ones.
This tuner does not look like an Elton but I am not sure what company made it or how old it is. I know this doesn't exactly answer your question but at least it is a straight answer. Some of our friends were having a little fun with you.
