I own one of these. Orange too. It is a Mondia. Swiss of course.
The ones I am familiar with came out of Ridgewood Cycle in Ridgewood NJ. The owner bought a bunch of these. Supposedly the bike was to supplied free in a deal with Finair so you could ride around Scandinavia and the deal didn't work out so the bikes were a surplus deal.
Here are differences on mine as I got it: Tahei seatpost, brown leather covered plastic base saddle, Sunshine HF hubs (old types with round holes in flanges), Wienmann 27 X 1 1/4 rims, Sugino Mighty crank, Shimano Titlest front der.
It is really the same as a regular Mondia frame of the period except for Campy droputs and fade paint job.
Great find!
