I think "vintage sound" is as much a marketing tool now aimed at collectors as anything else (along with the term "minty" ). I own a Conn 40B that is a good lead horn. It is from 1934, so it is definitely vintage but could be used today. I also own a Boston Chas. E George Vega that was a decent horn in it's day. It has a very tinny sound and really can't be used in anything but a band from that period. Both are "peashooters" in appearance and vintage/old.
