64yearsold welcome and i do remember Prolines and their CB. Yes they were bought out by Darton and Darton got whatever patents and dumped the little company a few years after that. I had a Point Blank one of the best hunting Bows around! Yer Bow hasn't been made in 20 years, unless you find one fer parts to help you out. Can't remember much about built in cocker. If you look good at it , see if the cords or strings hooks can be used off another brand and adapted. Shouldn't be real hard.
