Frame constructed with Agrati lug set "ROMA" pattern nr. 000.8020/E/U.

Headset looks to be OFMEGA.

Hubs appear not to match; is front Miche perhaps? Rear looks different from what can be seen in image.

Right pedal shows the remains of what was erstwhile a Lyotard Berthet.

Chainset model is called Gran Premio.

Do not know who would have sold this in the Bay Area at this time. Back in the '70's the Bay Area had several Atala dealers. Machine looks to be wearing a California cycle license.
