I have a boxed model 57 the tray has the screwdriver but im missing the 7 1/2 inch (9 1/4 inch with brass brush attached) and 3 1/4 inch bore swab. I would be very pleased to know if someone has either to sell. Thanks!
Good luck on your search! Try Ebay. Also go to the largest gun show you can find. I have found impossible to find items at several gun shows and on ebay!
