Classic and Vintage Bicycles: What's it Worth? Appraisals and Inquiries - Gardin road bike

Hello, this bike was owned by a family member for several years, but I don't know much about it. I can't seem to find the model number anywhere.
The frame is 22" and all the parts are Campagnolo or Shimano.
Any ideas what it may be worth?
Here are some pics.

What model Shimano and Campy components? There are many grades from low end to high end? What grade of frame tubing (my computer can't open your pics right now).

From what I can tell from the pics, its quite a mix of components (hurts value). May be a case where the parts are worth more than the whole.

Thanks

Looks an intresting bike so I did some seaching and found this text

'Joe Gardin started as the Canadian importer of Cambio Rino bikes, around '82ish, and they were made in Ossona, Italy.
Again, similar to Miele, Gardin set up a framebuilding facility in Toronto (which still has the largest population of Italiansliving outside of Italy)
The Gardin bikes varied in quality.'

Your bike has a complete mix of parts, if I was buying the bike I would like to know what hubs those are, and if there are any stickers on the frame saying 'columbus'

Hello,
yes, it has a sticker that says Columbus - is that bad?
the hub (that's the centre of the wheel, right?) is Shimano and the rims are Mavic and say they are made in France.

As far as I can tell the only Campy part is the rear Q/R mechanism. What type of mechanism is the front? Hubs look like 600ex.

I hate to say it but in that condition your looking at $125-150. Its rough, very rough.
