I have a Martin Onza bow that I just got at an auction. I know nothing about them and would really like some info on this type. Model number and whatnot. Looks like the book is from 1995. I searched for Onza bows and none of them had wood grip/panels. SEE PICTURES. Thanks so much for any help you could lend.
My guess is it is a 1995 ONZA M-60 with Ultra Sonic cams. You could try contacting someone at Martin Archery. Their web site is martinarchery.com, email is info@martinarchery.com and phone is: 509-529-2554
