Instandsetzungskraftwagen of Panzergruppe Kleist

A column of Panzerkampfwagen III (Ausf.D, E or F) leads a Panzerkampfwagen I Ausf.B ohne Aufbau, which has been converted into a vehicle to carry maintenance equipment for the panzer company’s repair and recovery sections, by the removal of its superstructure and turret. It was also known as “Instandsetzungskraftwagen I”. Note the yellow gothic “I” (which appears to be a “J”) that identifies the vehicle’s function, on the rear corner of the engine deck, as well as the white “K” of Panzergruppe von Kleist. Note also the small square tactical markings on the rear turret face of the Panzer IIIs and the racks for jerry cans on their rear decks.
