It's funny how when ever you see "light-weight" specified on a bike it never is - this is seemed un-butted gas pipe stuff!
Thanks again, Andy!
Your pics confirm to me that these were probably made by the same frame builder. The RD cable guide, braze-ons, lugs, fork crowns... even your brake mount is similar, minus the mystery nut on the bottom. One huge difference - no tubing seams anywhere here, and this frame is pretty light for steel! Is that a weld seam running cross the bottom of the bracket? Anyway... I think you've solved this mystery!
