This casing is the body of a Cesaroni P29-3G reloadable motor. It does not work alone as it needs the P29-CL rear closure to be a complete reloadable motor. By purchasing this case you can use reloads different from the ones you use in the Pro29 motor you own. If you don't already own a Pro29 high power motor you may want to purchase a complete motor set instead. Please look in the reloadable motors category in our webshop for the motor best suited to your needs.
