Detel Frame

Picked up this bike durring an internship in Minneapolis. They guy didn't know much about Detel Frames, and nor did I. But the guts were good and barely used. So I bought it. So far its been a dream to ride, but the frame is still a bit of a mystery. No real info out there except little bits here and there. http://budgetbicyclectr.com/1985-detel-marathon-road-bicycle If anyone knows anything else about Detel I'd be more than happy to hear!
