A little of your knowledge perhaps?
Hello I recently bought a bike but I haven't the slightest idea of what the frame is. all of the paint has been removed and the head badge as well. The serial number is M7B01567 and it has Suntour GS dropouts. The lugs are long and pointed on the top and round on the bottom. Thank you much for the help.

A few bits that might help someone identify the bike:
There appears to be a rivet in the head tube. Can you get a shot showing the front and all the rivets? Their location and spacing can often help.
Seatpost diameter. This might aid in a tubing manufacture.
The wrap around stays and that fork crown should help a bit, but I'm not certain what to link them to.

Nope. It would be marked on the seat stays where they join to the seat tube.
Frankly, I doubt it's worth doing anything with it. If you send it to me I will properly dispose of it for you.

it sure seems Japanese but: that 26.4 seatpost is odd. Either it's a heavy gauge tube (and doesn't look like it being all chrome and with nice lugs and forged DOs) or that's a metric seat tube.
Are you sure it's the correct size post?
What's the BB threading?
Suntour GS dropouts were more common on JP frames, but there were a number of EU builders who used them (and Shimano DOs as well)

Peugeot perhaps? Not likely to be a Nishiki, at least according to Sheldon Brown's Seatpost Size Database. Then again, could be 26.6 as well if it had an incorrect post included.
Edit: what's the crankset that is sticking in the mud?

Its not mud, its fine soil. Its a Sakae cr but who knows if it is the original. I bought the bike as a fixed gear that some one had "created". It does however have a Tange Falcon headset that is probably the original.
The seat post that come out of it is a 26.4 but it may be the wrong size and I am not sure of the bb threading but that would make it easier.

Bikes: See my sig...
Looks like mid eighties Japanese manufacture and could have come from any number of makers as the frame bits are pretty generic... if it was an upper end Nishiki or Kuwahara you would see these marking on the seat stay caps.
May be a bike that was built on contract and sold through another dealer... 26.4 could probably indicate French manufacture and am wondering if any Canadian Peugeots came with GS dropouts.
Bottom line is that it looks like a fairly decent mid level frame.

Did I miss the BB size? Centurian?

Serial number indicates a 1977 Mikki built frame. The two major brands built by Mikki during this period were Centurion and Sekai. The cinch slot on the seat lug looks pinched at the top by about a millimtere, so the proper post is probably about 26.8mm which would be correct for a Tange tubeset. To the best of my knowledge, Sekai did not use a riveted headbadge during this period. The holes are consitent with Centurion's headbadge, while the chrome and wrapover stays are consistent with a Semi-Pro model.

The lugs and fork detail remind me of my father's SR, 1980 give or take. Good luck. looks like a fun project.

Edit: And he's quite correct, I can confirm any frame of that level if it was a Sekai would have had a painted headbadge.
