Ah! Based on your close-ups of the component and additional frame detail, I take back my comments, regarding that the bike could be of a lower quality. What I now see, again thanks to the detail shots, is a bike that I would like to have.


The one the OP shows is a fairly high end offering(if not top of the line) and the vintage suggests that your estimate of the vintage is pretty close to the mark. However...

In 1961, Universal introduced the center pull Model 61 caliper. One(meaning me) cannot help but wonder why a top dog, in the Atala kennel, would not go for a Model 61 as opposed to the older Universal side pulls? Perhaps this is the number two dog offered in the Atala line-up, differentiated only buy the component choices.

At any rate, I would jump at a chance to find a bike like that one. A more than worthy steed and project.
