Long story on this, but up for the cost of postage (figure $30-ish in the continental USA) is this Centurion Ironman frame. 58cm ST CTC, 57cm TT XTX. Red and white, small-ish dent in the downtube (I found it by feeling). It's an '86, so came with Shimano 600 SIS and has the sloping crown fork.

It's filthy and needs lots of touch up (or a respray/powder coat) but as they say, good bones. English BB threading, 27mm crown race for the headset. Comes with the Sugino seatpost binder bolt and a pair of rear dropout adjusters. It's straight, just needs some lovin':
