....well made and collectable frames, Constante Giradengo was an Italian champion from around 100 years ago who won many classics I'm not too sure of the frame numbering sequence but yours certainly has the look of a 1940/50's build, some further info on the marque << https://utahrandonneur.wordpress.com/th ... engo-barn/ >>
