why do you say that model? i was also thinking the '8106' on the seat lug might mean june, 1981, and the original owner was off by a year.

I'll try to look at my serial number to help corroborate year. I suggested touring elite b/c the components and seat stays were the same and b/c I hadn't heard of the competition before. It could very well be a competition. I haven't seen any images of that model. Your frame does not have brake cable guides like mine does and it might also have slightly shorter chain stays. Anyway, these two models are very similar siblings from the look of things (& without frame specs and measurements to establish the other differences between the models).
