I think that's a '69 Mercury Hunter. In '67 and '68 the Hunter wwas part of the Sovereign line, model 1096 (the Sovereign line was dropped in '69). In 1970, the logo went to "ben pearson" (lower case) with a bison hoofprint. In '71, the model number was 7346-0. I have 4 Mercury Hunters and a Mercury Marauder TD. Two of the Hunter's have your logo and one is marked 1096, the other has been refinished(?). One Hunter and the Marauder have the lower case BP (I would guess 1970). The fourth hunter has no logo and no model #, just draw weight and serial number.
Archery Archives is the best-only???-source I've found for IDing Pearson bows. PM me if you want the links.
From top to bottom or R to L (all dates are estimates):
1. '67 or '68 Sovereign (refinished? data missing)
2. '67 or '68 Sovereign
3. '70
4. '82-'84
