definitely not a Montello. Somebody made a real mess of the replacement decals and not a drive side photo in sight. Post some, especially of the rear, drive side dropout and underside of the bottom bracket shell. I can't ID the components but the brakes look like Gran Sport. I think it is older than 1985 but still 1980s. What size seat post does it use? Are there helical ridges inside the bottom of the fork's steerer? Is there a patent number on the rear derailleur next to the cable housing seat. What's the symbol and number on the back of the crankarms? What the CAM numbers on the back side of the hub locknuts?
