Too many good ones from the 50's through the 70's from Bally, Williams and Gottlieb. The well known ones get their respect, but the more obscure titles can be just as good or better. You just don't have many seeking and playing them. Of the pins I've played...
50's-Criss Cross
60's-Buckaroo ties with World Fair
70's-Surf Champ (Atlantis#2 but I think it just humiliates me too much)
