I got an old PSE compound bow from my uncle, but as is usual with old equipment, some things were missing. I'm looking for a manual, year of manufacture, model number or anything that will help me get more information about this bow. Specifically I'd like to decrease the draw weight from 60lb to 50lb, as I'm not yet quite strong enough to comfortably use it at 60lb. Someone was worried about the lack of a cable guard, but it looks to me like this is a bow with a single string instead of separate string and cables, which might be why there's no cable guard.
