I was basing my request on a page from a Pearson Catalog (I printed it out) on the now defunct Archery Archives website that shows 100 gr versions of the 781 (barbed) and 782 (sloped) broadheads were available in 1957, both 4x4. Wade Phillips' book shows a barbed and sloped 4x4 (shorter than the 1947 and 1950 versions) were produced in 1953. My Joe St. Charles compilation book shows that the "short" 781 and 782 were introduced in 1953. Do these dates indicate the first year of production or the only year of production? I haven't had any luck finding anything specific for 1958. I had hoped the BH's introduced in 1953, and shown as available in 1957, were still used in 1958.
