New barn find that I need to learn more about.

PERFECT CYLCE MARK II

I haven't been able to find much of anything about that brand. I was trying to date it based on the components, which are all Japanese, and the best I can do is guess its probably '75-'85. Pretty lame estimates.

Detalis
Dia-Compe Brakes.
SunTour parts.
Schwinn Pedals.
Silstar 165 Cranks.
Sakae is also on the crank bolt cover.
The frame has a "hand made" sticker.
And pretty sweet lugs all over.
Serial Number under the BB is: F1C31612

My bud thought it could be a good find. If it becomes worth it Im going to strip it down and rebuild the frame/fork into a custom fixed gear. I just want to know what I have, and what its worth (if anything).

thanks all.
