Here's some info I gleaned from an earlier post on this subject:
Wing Archery (Bob Lee) 1951-1968
Head Ski 1968-1969
AMF 1969-1974
It also stated that Bob left in 1973,inferring that he may have contributed in an advisory position,at least.That's the extent of the notes I have regarding that post,can't recall the author,but someone else may be able to shed more light on the subject.I have a 58",47# Redwing Hunter (Head Ski era)& a 62",50# Falcon (AMF era),both nice enough bows in their own right, even if not as desireable from a collectors' standpoint.
