I'm trying to find any info anyone has about this Wilson Brothers recurve bow. It is 68" and 35@28". RH black riser. Cream colored glass. Merrill bow sight attached with screws on back of riser. Limbs are straight. Overall very nice condition. Serial number indicates 1962 manufacture. Belly is marked Black Widow, Wilson Bros and handcrafted for Maple Grove Archery Shop. Ultimately this bow will be sold, but I'd like to get input on how many were made, quality and value. I can't post pics, but I can email them. Thanks!
