The frame's bulge-formed head was likely produced by Nikko-Sangyo.

Are you able to post any additional images?

Spots such as dropouts, seat stay attachment, bottom bracket shell would be helpful to readers.

Thank you very much for the additional photos. ;)

Good job with them; they should help readers to help you.

Have never before seen these dropouts; no guesses as to their manufacturer.

The bottom bracket cups suggest bicycle was made with a Thompson/Thun type chainset.

The bits of green which can be seen on the bare metal indicate a zinc chromate primer.

Do you have the bicycle's fork, or is it missing?

That chainring looks like it could be part of a Shimano Front Freewheel set-up. Early '80's?

I have a Suburban five-speed with that set-up, I found it easy to use, not sure why it never caught on.
