I picked up a weird frame in trade yesterday. It's a large steel frame, looks to be either road or cyclocross, and has some very small cantilever brake braze-ons (though without studs). It came completely stripped- no bearings, BB, cups, fork, or even the studs for the canti brakes, and has been painted poorly a couple of times (possibly why it was so stripped).

The only clue is its intact headbadge, which says "Space Pac", one word above the other. Anyone have any information on this bike? A Google search doesn't give much, one person asked on BF a few years ago and didn't really get an answer. It weighs around 7lbs and has very nice lugs, so it's not a department-store bike, but there doesn't seem to be any way to identify it.
