I'm seeing mismatched and incomplete decals. It's definitely a frankenbike rebuild. Regarding the frame itself, the embossing in conjunction with the eyeleted dropouts, exposed brake nuts, single bottle bosses and cable routing running over the BB shell suggests a circa 1982-1984 mid-range frameset, such as that found on the Nuovo Racing. I don't see anything to support it being a Specialissima or a Professional. If you could obtain the serial number, that would go along way to determining the model and what is/isn't OEM.
