Need help to identify 80's frame (probably Miyata?)

[caffetito]

Hello, I am trying to identify this frame. According to the seller, it is Koga Miyata with Tange Champion nr. 2 tubing and Suntour Superb ends, but I haven't found anything similar in 1984 or 85 catalogues. The serial nr. is M0C0057 so it indicates it was made in 1984. Do you have any idea what it might be? Thanks

The serial number could also mean it's a Miki-built frame from the third month (or fortnight) of 1980. They built frames for various brands, but - obviously - not for Koga-Miyata.

Very nice frame, BTW.

Thanks a lot! I'll have a look at Miki
