The Seburo Bobson Centennial is a fictional, blowback operated automatic handgun, used frequently in the Appleseed manga    by series heroine Deunan Knute,  alongside a Colt M1911 style handgun.
Approximately the size of a Walther PPK/S concealed-carry pistol,  the Bobson uses 6 millimeter bullets, fed from a 23-round capacity magazine conventionally loaded into the hand grip. Bobson 6mm rounds are HV-class (high-velocity) in nature, and are suggested to behave similarly to 10mm rifle ordinance. In appearance, they are much slimmer than traditional 9mm handgun bullets, and also significantly longer. 
Ignition is provided by a double-action trigger, which releases a striking hammer.
The Bobson is designed primarily for right-handed operation, as the shell casing ejection port is located on the right side of the weapon.
One of Seburo's first designs, dating back prior to the arm-maker's acquisition by Poseidon, Centennial Editions are in limited production around the year 2126, featuring a prominent signature along the right side of the handgun's blowback slide.
Notes and ReferencesEdit
- ↑ In the 2004 movie it's unclear whether or not Deunan's "memento" handgun, previously owned by her father Carl Knute is actually a Bobson, owing to several deviations from the original design, most notably the overall size of the weapon. That said, a prominent triple-circle motif on the pistol grip confirms it is some kind of Seburo.
- ↑ Also, In the manga series (the end of Prometheus Unbound), Carl Knute is said to have used a Steyr G8 9mm handgun during his police career, and not a Seburo.
- ↑ In Ex Machina, Deunan appears to have foregone Seburo altogether for her choice of sidearms, and uses a Glock style handgun instead.
- ↑ The Bobson isn't seen until The Scales of Prometheus, but goes unnamed until the short story 26 Called Game, featured in Appleseed ID.
- ↑ Based on the size of the weapon as compared to Deunan's hand. Also, fanbase built replicas of the Bobson are frequently constructed using Umarex PPK/S airgun frames and a base.
