full name seems to be Eurociclo - Castenaso - Bologna
above transfer dates from 1970's
next step might be to determine if the entity is an actual manufacturer or if it represents a house brand for a retailer
cycle appears to hail from the early 1970's so there has been a half century for any entity behind it to have ceased play
perhaps a forum member who is fluent in Italian could try telephoning the number on the above transfer to see if they be yet in operation

EDIT:
name appears to be that of a retail shop
here is an advert from 1971:

you do not state clearly if cycle in your possession or not
me guess be not
if in your possession you could make some closeup detail images of spots such as joinery of taper tubes to ends, bottom bracket shell, seat cluster, bridges, etc. which would be helpful to a frame detective such as
MauriceMoss
another avenue to explore would be to look at cycle examples produced by makers in and surrounding Bologna
