It's an all glass bow from roughly the 1950's. Would anybody know anything about the string length?
Measure the bow length, nock to nock on the belly side of bow, and get a flemish twist string that is 3 inches shorter than that. Some of those old Bunyan bows had static tips or recurves....some straight limb. The recurve models should have about a 7" to 7 1/2 " brace height....straight limb models about 6 1/2. Adjust by twisting string.
Thanks.
