Hi,
Many fighter pilots on both sides affected the use of walking sticks as a bit of panache. The only reference I've seen to a true "victory stick" is in the caption to a photo said to portray Gefreiter Erich Mix of Jasta 54s, in an article by Christophe Cony and Pierre Martin in "Avions" magazine, No. 74, Mai 1999. The photo shows a pilot and mechanic of Jasta 54s in front of a Fokker D.VII marked with a 'V' insignia, enclosing a skull and crossbones. The pilot holds a walking stick which the caption says is an 'abschuss stock'. The captions mentions two white stripes on the stick (though I cannot make them out) and says they denote victories. I have used this photo myself in two publications, captioned as Erich Mix (and his abscuss stock) and his aircraft, though I am now reliably informed by an eminent historian that the pilot in the photo is actually Ltn. Vogt of Jasta 54, and not Mix! (This would help explain the 'V' insignia). As Vogt had only one confirmed victory, the striping of the cane or stick to denote victories becomes something of a moot point.
Ed Ferko revealed that when
Jasta Boelcke received their Fokker Triplanes, "with his usual flair, Fokker had sent walking sticks turned from scrap propellers for each pilot." These walking sticks show up in various photos of Jasta Boelcke pilots, but I've never noticed that any were striped to denote victories.
Then of course, there is the famous 'Geschwaderstock', the knobbed stick of Richthofen which was passed down to Reinhard and Goering. According to Alex Imrie, this was a "gift from some Unteroffiziere who had carved it while under enemy fire in the front-line trenches." Richthofen prized it because it affirmed his bond with the ordinary front-line ground troops.
I would imagine that walking sticks in other units came from a similar wide variety of sources, and that some were probably made by the flying unit's ground personnel themselves.
