An incredibly weird layout of a Storch undercarriage . A experimental modification for use on very rough or muddy landing strips, it stops the wheel "digging in"

The true origin of the "shark's teeth" on WWII fighter aircraft...

Not the P-40s of North Africa. Not the P-40's of the Flying Tigers in China.
 The original --- German Bf 110 fighter aircraft of squadron ZG 76
Infact,shark teeth appeared even earlier,in WW1 with the German flyers,  see photo of Roland CII
