I Bought A Mystery Vintage Race Bike? (see description for answer)

I bought this vintage race (?) bike today off of Facebook Marketplace. And I am trying to find out what the heck it is. It has a lot of interesting points.
The bike is a 10 speed. The 63cm frame is lugless steel. I believe the bike is from the early to mid 70s. The bottom bracket seems to be sealed bearings. The derailleurs are a Shimano Crane in the rear, and a Shimano Titlist on the front. The wheels at 27" with Campagnolo high flange hubs, and Rigida clincher rims. The leather saddle is an Ideale Speciale Competition 90. The seatpost measures 26.8mm. The stem quill is 22.2mm, so not French. The bike as is weighs about 25.2lbs. The tires (maybe not original) are a Schwinn 250 Super Record, and a Schwinn HP Le Tour.

ANSWER: It is apparently a Viscount Aerospace. It originally came with a cast aluminum "death fork" that was know to fail. THIS BIKE HAS A STEEL FORK, so apparently the original fork was replaced. The "V" logo on the components is for Viscount.

And I think it IS the original paint. The blue on the seat tube normally has decals over the ends of the blue paint.
