I believe what you have is a Mercian. I have a frame with identical lugs, looks to be almost the same size too. Mine however, has no braze ons what so ever and a re tapped BB. The lack of braze ons and cable guides makes me believe it to be 10 to 20 years older than this frame but like I said : identical lugs. What do the lugs on your brake bridge look like? The fork ( my fork, org. one that is ) has a inner dia of 22.15 not 22.2 , I suspect that fork (yours ) is a replacement, I replaced mine as well recently. Do you have a serial stamped anywhere? Mine is without. I got the bike as a trade of sorts at the shop I was working at in ABQ NM. The paint has been stripped off, poorly re painted and then looked to be stripped again. Despite its looks, it is my fav. around town bike, very sturdy and smooth. I built it up low cost with an internal 3 speed/coaster , seeing as the rear spacing is 120 mm. Could you post more pictures of your bike? Since owning mine its been a real puzzle on make and origin, but after seeing this post, and looking through older Mercian photos I do think the ( my ) mystery is solved. Their lugs have varied and changed over the years , however the BB lugs seem to stay very similar. How interesting the life of a bicycle , if only they could talk!
