You may be able to read the stamping on the cups without using a puller. You'll see those style lugs on a lot of early 1970s Bianchi like the Rekord models.The bottle bosses look very high on the tube and were probably added later. I suspect this may be a Bianchi Rekord 71 with their hi-tensile tubing which was known as Tubi Calibrati 1-20.
