A secondary goal when considering additions to my spring powered air pistol collection was to find examples of the different cocking methods. Listed are the ones that I am aware of unless anybody can add something that I might have missed.

Barrel cocking overlever forward cocking eg Webley
Barrel cocking overlever rearward cocking eg Cogswell & Harrison Certus
Sidelever cocking eg Frank Clarke's Warrior
Underlever cocking eg Abas Major, Anson's Star.
Crank wound eg AG Parker.
Push barrel cocking eg Hubertus, Gats etc
Pull down cocking rod mounted in grip eg Diana Mod 1.
Foldable rod cocking eg Frank Clarke's Titan.
Break barrel cocking with frame mounted compression cylinder eg Tell 3, Diana Mod 5
Break barrel cocking with cylinder in grip eg Lincoln Jeffries Junior.
Trigger guard pulled down cocking eg Haenal 28.

Please excuse the probably less than accurate terminology, but hopfully you will know what I mean.
I have not included different linkages used on some models to achieve the same basic cocking method.
