In the context of, yes. One definition of vintage is simple "not of the current era". As the 6 ply shell is not a current production shell, and the blue/olive badge went out-of-print, replaced by the Monroe badge, and then re-issued. They weren't built in the 90's or the current decade. Clothing works the same way, anything from another "era" can be vintage. In terms of wine, where I believe the word originated, "vintage" simple means 75, 85, or 95% of the wine in a dated bottle must be from that year. Depends on who's scale you're using, and in what country you're in. Hence, you could be drinking a vintage wine from 2007, 1997 or 1957. Some hard-core car snobs might hold fast the term "vintage car" to mean the years between 1919 and 1930, and no other years. But there are plenty of car shows out there every night and/or weekend that hark vintage 40's, 50's, 60's, and 70's.
