Kelly, to summarize from the pics you sent to me in an email, the bow is a Wing Thunderbird 62", 53#@28, Serial # T7-3276 written in white ink, is an all black phenolic (called "bowflex") bow, with no quiver inserts and is made by Wing Archery but not Head ski nor AMF. I beleive that it is a late 1968 early 1969 just before Wing was sold to Head Ski. They were located in Jacksonville, TX. You can find a bow just like it in the Wing Catalog X which I believe to be 1969, however, Catalog X was put out by Wing Head Ski, so it had to be before that catalog came out.
1970 and later, the company was owned by AMF. they began putting quiver inserts in the back of the bow riser. 1970 bows were bowflex and a S/N characterized by TAXXXX.
Anybody have a 1968 Wing catalog ?
Hope that helps.
