Noticed a Guerciotti on Dale's Classic Rendezvous site that has internal top tube cable routing. Trying to date another Guercciotti that looks very close and wonder if Dale or others can suggest the date of the bike on the site, or suggest when Guerciotti would have been using internal cable routing.

I know that dating internal top tube routing came up recently but it was inconclusive.
