Thanks for all the info. I did some research on Chiorda. I think a possible origin is that it was made for JC Penny or Ward's or someone like that, etc with the name Bergamo emphasizing Made in Italy as sort of a slightly more upscale model. Chirorda was based in Bergamo it appears. Also, the bike is older than I thought it was. I would guess now that its somewhere around the Mid 60's.
