Hello...I bought a bunch of stuff from a local sporting goods store going out of business. There is a box of assorted bow strings that I can't find any info on. They are in clear plastic bags (3"x3") with a card that reads "Robin-Hood-Archery", and "M-95-DL 56 Bow". I assume the number 56 is a length as there is also other numbers. Any info would be appreciated. Thanks.
