Nothing like resurrecting a six month old thread. I just picked up a 513T from an estate last night for not much money, thinking that it looked a little rough around the edges. Still, it had a nice old Redfield target peep sight with and adjustable aperture and the barrel looked good. After cleaning things up with some WD40 on some fine steel wool, it came out far better than I expected. The trigger pulled at about 5 lbs. Your instructions on adjusting the trigger were spot on and I was able to get the pull down to a more reasonable and safe 2.5 lbs. with litle overtravel. Should be a fun shooter.
