Mystery cinelli track bike identification
So I'm in the process of possibly purchasing this bike but need help identifying what it is. Owner says it is 1950's cinelli track bike that's been repainted.
Lugs look like they have elongated hearts on them like de rossa, but bottom bracket has cinelli s.c. Stamped into it. There are also five small port holes on bottom bracket. I was thinking it was possibly cinelli sc track bike, but there are also holes drilled into fork and frame for brakes.
Need a cinelli buff to help me figure this one out! Thanks in advance/pics below
