Welcome to the forums. I believe that the "C" is an incomplete zero. F5076264 would make it July 1985 manufacture by Fairly of Taiwan, a known source for Diamond Back BMX models in the mid 1980s.

When you said, "There are no DT bosses, just the locator for the campagnolo clamp on DT shifters it has", I took it to mean that there were no bottle bosses, as they are typically located on the down tube. Tube and chain stay ends are rarely mitered if the BB shell has flat ended sockets. This socket style allows more contact area for brazing of non-mitred tubes and chainstays.

Sorry, I don't know the manufacturer who used this format. It could be Japanese but I'm not sure. There are probably dozens of 1980s Japanese manufacturers who aren't covered by the guide.

long time listener ! First time caller :)

Greetings from the antipodes !
Hope all is well your side of the world .

Bought a frame recently .
Original owner thought it may be a Shogun ?
HAs had a bit of a life . Painted over etc .
Anyhoo it has a serial number on the bottom of the seat tube ....
Also seems reasonable quality ?
has those slightly annoying Shimano lever bosses .
I have the same on my Koga Miyata Roadwinner
26.8mm seat post
126mm OLN rear
No top tube cable guides ( maybe removed ? )
Had forks with it that I dont believe are correct as they had no eyelets but rear do ?
Pics attached .
Any help with possible identity gratefully accepted .

Cheers

Based on the serial number's format, its location and the frame characteristics, my leading candidate would be 1985 manufacture by Pacific Cycles of Taiwan. In North America, they are known primarily as a contract manufacturer for brands such as Lotus, Mikado, Nashbar and Supergo. They also have an eponymous brand, though I don't know if it extends as far back as 1985. Unfortunately, I don't have any appreciation for what brands they may have been marketed under in New Zealand.
