OK. I got a Mercian 631 frame to build into an audux-type thing. Thing is, its got no number stamped anywhere, although I haven't had a look at the steering column yet. Is it not really a Mercian? Or can it be that the BBs or seat tubes weren't stamped at some points? It's an early Audax, I'm guessing its late seventies ... band-on shifters, horizontal drops, flat crowns with nice V shaped lug thing on top, simple long lugs, some with trianglar cutouts.

Any clues, people?
