Rossin serial numbers?

I found a Rossin Record on Chicago CL today. It's too small for me (57cm ctt), so I'm likely to part it out, saving a couple bits, moving the rest on the people who need them.

The frame seemed to me like an early- to mid-80s. It has brake cable housing and shifter braze-ons, but still uses a clamp on front derailleur. The right rear dropout is drilled for a Portacatena unit (suggesting early 80s). The outside of the left rear dropout is stamped "NK" and "87". I can't believe a frame made in 1987 would have a Portacatena and wouldn't have a front derailleur braze-on, so I'm skeptical that indicates the build date.

I wasn't able to find anything else on the frame that looked like a serial number to me.

The parts don't seem to be a great indication of its age, being a mixture of various Campy 8-speed Ergo bits, likely added later. I originally thought the frame had been cold set. Perhaps it was a bit, but it measures 126.75mm with my calipers. The hub measures 130.

Some other images:

Any guesses as to the age? Thx...
