Claims 17 and 19 stand rejected under 35 U.S.C. § 102(b) as being anticipated by
Larsson. This rejection is explained on page 2 of Paper No. 11 wherein it is stated that:

which shows a housing (2), a spring biased striker (22), a cocking and trigger
assembly comprised of first [sic] a first lever arm which is rotatably mounted to the
housing through pin (43), and a second arm (47) pivotally connected to the first
arm through pin (45). The front of housing (2) is rotatably connectable to the
