This bow was made for my father back in the mid 70's. It has an aluminum riser and what appears to be maple and black glass limbs. At the time we lived in the NW part of PA, just south of the NY state line, between Warren,PA and Jamestown, NY. I believe the bowyer was in western NY, but that is based on what I remembered my dad saying. The limbs are marked with the name "Marz," which I'm wondering if that is the bowyer's name. My dad died in 2013, & I re-discoverd this when cleaning out his house. I had borrowed it from him in the 80's when I said goodbye to compounds, and returned it to him when I bought my first bow (a Bighorn.) You can click the link below and you'll go to my photobucket where there are pics of the bow. Thanks in advance for any info!
