Just picked up an older all black widow. 58" serial number 16085. Sweet shooter.
E-mail Roger @ Black Widow the serial number and he will tell you the date the bow was SHIPPED from Black Widow.I got a couple of the old Wilson BW's, and got the info in just a couple of day from them.
Thanks, I have been told that it was made in 1966. Black and rattlesnake skins looks awesome.
