The pantograph on the fork crown is that of Sannino:







All the Sannino frames I've seen with this style of fork crown also had "Sannino" engraved in the bottom bracket shell. Like this:



Also, the cutout here doesn't ring any bells for me, unfortunately. So, based on just the pic of the BB shell, I'd say the frame is potentially not a Sannino.
A few more detailed pictures of the frame might help in possible ID.
