...the actual maker of many Italian bicycle cycles is one of the grayer areas, somewhat shrouded in mystery. For example, I know that the brothers who made and sold Rauler bicycles did a lot of work for Colnago, so made some of those. Similarly, a lot of contract building has gone over the years, to the point that a name is not a good indication of the actual manufacturer in many cases.

Yours has enough pantographing, for example, to be reminiscent of many of the Rauler productions. Someone else probably knows more than I do.
