Based on what I see, and my eyes are getting old, I would suggest that the bike is an entry level model that has experienced considerable alteration. I should be cafeful with sharing information about the OP's bike based on that single picture. I would like a closer look at the modified rear drops, not to mention other details. That said, this looks to be an example of an entry level Chiorda of late sixties or early seventies vintage...



Based on what I see, the steering stem is set too high, the rear brake cable top tube clips are position wrong and the fork looks to be bent forward slightly. I might add that if it is an entry level Chiorda, those forks are very fragile and I say that from unpleasant experience.
