BSA

To get the correct part for your PRE WWII BSA you must have and consider the Model Name, Serial Number, and Caliber.   The size of each part varies according to the Name, Serial Number, and Caliber for the early BSA and Lincoln Jefferies airguns.  Because we sometimes buy unlabeled parts mixed and/or in bulk we cannot always provide this type of information.    Therefore, if it is not listed in the description, we do not have the information and cannot guarantee that it will fit your specific air rifle.
