Well folks, so far all of the brand suggestions have reached a dead end. None of the brands thus far have a serial number format that matches mine. How often does it happen that we don't identify someone's bike? I guess I'm so used to most of these mysteries being solved within 10 replies that I never imagined mine would be that odd.

As far as the China bicycle company goes, I can't find much about them or the bikes. I'm sure these left side cable guides will unlock the mystery eventually. Until then, is it safe to say we are possibly stumped?
