There could be chrome underneath that bad paint, so in addition to being a Super (I'm thinking '82 - '84), it may also be a Nuovo Mexico from the same time frame. Certainly a bargain at the price you paid, and surely worth getting a repaint. The money saved at the outset would defray a lot of the paint cost.
I believe the PO bypassed the under-BB cable tunnels because the corresponding braze-on cable stop at the rear of the stay appears to be missing. Of course, he could've run them underneath and inverted the clamped-on cable stop. The mysteries of what POs were thinking before we got our grubby little hands on their old bikes...
Very nice score
