Well the rattle in the cocking arm anyway . I did some searching over on the yellow and found this is common with a few fixes suggested , the one I liked ; The simple one : is to open the breech and on the underside , apply a cut to fit strip of the hook part of some sticky back Velcro . When closed , no more rattle . Going to have to open her up and apply some tar on the spring ,to get rid of the Buzz. kirby
