I love those guns! IMHO the Hurricane and Tempest "family" are true classics. Along with the FWB 65, those are two air pistols I'd never be without.
Interesting trivia: the alloy grip / frames for the Hurricane and Tempest were cast in molds that did two at a time, ingeniously trapping the steel cylinder inside. All are actually "born" as Hurricanes - a Tempest required the extra step of milling the rear "tail" off. The only other differences are the front barrel shroud casting, and name on the fore end sleeve.
Yours is a late production example. The nice wide trigger blade and slightly shorter front shroud give it away. The beautiful wood aftermarket grip is another plus - beautiful pistol!
The traditional way to cock one of these is show in this pic from the linked manual - hold it out in front of you, with the frame in one hand, and the other hand reversed so your thumb is near the muzzle. This makes efficient use of the muscles in your chest and both arms.
