literal gaspipe may very well refer to high-tensile steel, but I've heard the term "gaspipe" used a slur against any no-name, straight-gauge steel tubing. Commonly found on old huffys, etc.

Both the Milwaukee and the Surly are double-butted 4130. Both take long/standard-reach brakes. Both have 1 1/8" steerer tubes and threadless forks. Both can fit relatively wide tires for a track bike(32's on the Milwaukee, 38's on the Surly). The Milwaukee has a water-bottle braze on.
