RE: Help identifying older Browning bow ...
Should be a label on the limb with the serial number, draw length, weight range and let-off and string length.
Dang! I hate when guys remove them. My brother is the worst offender.
Just count the number of strands and measure the string. Subtract about a half inch and that should get you close. Strings stretch, so if yours measures say..32 1/2" you probably need a 32 inch string. Get a string with the same number of strands also.
