Does anyone here know about Italian made racing bicycles??

I got a racing/street bicycle from the 70s. Trying to research it to figure its value. The wheels and tires, pedals, and seat are NOT original but the frame, gears, and pedal lever cranks are. Hand made in Italy.

Does the brand Campagnolo ring a bell for the gearing? Stronglight? Frame is Atala milano. Handlebars Cinelli

Wheels are Sovos Weinmann USA.

Can someone interested or otherwise knowledgeable help me out here. Shoot me a PM or something and I can send pics by email. A guy at a bike shop once told me years ago that it would bring $2000. Know idea tho. It had "Look" pedals originally that I sold on ebay, now just Specialized pedals

thanks
