This seller claims that the group set on this funky looking frame, excluding the brake levers, handle bars, and quill stem, is 6400 series Shimano 600.
The quill stem is a 130-mm Nitto Pearl. I'm not interested in the frame, brake levers, or handle bars; it's the 600 parts I'm after for a potential build.

I've researched Sanwa and found that Sanwa made everything from very low end to somewhat highish-end stuff. Could the bike in question actually sport the 6400 600 series? I don't want to ask the seller to prove they are 6400s by posting more pictures (don't want to question his honesty). The pictures are sh*t, but the crank set looks like a 600. Here
are the pictures:

Current bid is about $66.00.

This might help in comparing pics: for sell vintage shimano 6400 groupset, all parts included

Well the pictures you linked to aren't 6400 (600 Ultegra) but 6200 (600EX), which is two generations early (or three generations, depending on how you interpret the Shimano chronology). As to the Sanwa, it does look like 6400 derailleurs and crankset. The pedals definitely aren't. Hard to tell about the rest.

Edit: I see the posting mentions 7 speed. That should definitely make it 6400, circa 1988-1991.

Sorry about the bad reference for comparison. Thanks for the input T-Mar. You've been such a big help for all of my inquiries of late. Much appreciated!
