I always thought the Teisco's pumped out a lot of very cheap/budget. They could have landed the Sears contract. Some were made of plywood etc.. however they did come up with some really interesting designs and i believe they had higher range models as well. Mats made (Matsumoku) i feel were a step up usually in quality. The serial number plate looks like its from an old Mats made guitar, but the rest doesn't so it's probably a hodge podge partscaster of many different guitars to make one.
