Hi all. Just picked up this bike from a thrift store. Tearing down the bike to reprint the frame as its got a few rust spots.

I'd love to know what bike it is but it has no serial numbers, decals or badging. I have checked every conceivable place and no luck. The wheels are Weinmann 116 alloys.

At a total loss of where to start identifying it and was hoping someone could share some light. See pics.

Thanks!
