I recently picked up a very neglected old Atala at a rummage sale, and am having a lot of trouble identifying what model it is and what year it's from. The only Atala catalog I can find is from 1971, and this doesn't match up with anything in there.

It is very lightweight for something so old- the seat post, stem, and handlebars are all aluminum. The stem is stamped "ttt" on one side and "MADE ITALY" on the other- I saw in another thread that this could date the bike to the late 60s? The crank is steel and has no identifying markings. The rims are aluminum but I'm pretty sure they're aftermarket (japanese brand). Derailleurs are Simplex, but I can't find anything indicating what model. The shifters are mounted on the downtube. One of the rear derailleur idler pulleys is marked "L.J. SIMPLEX BTE S.G.D.G." (the other is SunTour and is obviously a replacement). The 5 speed rear freewheel has the markings "MERATE REGINA G-S CORSE S-I-C-C." The brakes are Universal, with no model number I can find anywhere. The brake levers have leather hoods that are in absolutely awful condition. The serial number is S721780 and is located near the top of the seat tube.

Any help identifying this bike would be greatly appreciated. I'd also like to determine what I should ask for it when I attempt to sell it (after it's been cleaned up and gone through, of course). There's no way I can keep this one unfortunately, I tried riding it and I'm too fat and inflexible to comfortably reach the downtube shifters and the brakes without extension levers. I'd like to get at least $100 for it, is that a realistic goal considering I live in Ohio and it's almost November?

I have taken several pictures, which can be found here: https://imgur.com/a/Bagt1

Anyone?

I was able to determine that it has Simplex Prestige derailleurs, the revision that was released in 1965. So I'm guessing the bike is 1965-1970. Still don't know what model or how much it'd be worth, though.

I could not get $100 for it in its current state. Its close to an entry level bike, not complete, with bottom of the line and rusty components and parts.

It would appear that you have one of Atala's entry level models, perhaps an Atala Corsa or a North Star(I remember seeing a model named that or something close to it). These bicycles are almost utilitarian in nature but still offer a nice recreational ride quality.

They are in the same category as the Toapado, Chiorda and Bottecchia entry level bicycles offered during the sixties and seventies. You can learn how to determine vintage by applying some of the information contained in How Old Is My Bicycle?

Determining the Vintage Bicycle Value is a bit more difficult, perhaps even impossible, since there is really no way to tell what someone will pay for an old bicycle, these days. If you do spend some time learning how to determine value, you will come to realize that many things impact vintage bicycle value and some of those things have nothing to do with the bicycle itself.

Hope this is a help.
