In the MAN commercial vehicle guidebook "Leistung und Weg: Zur Geschichte des MAN Nutzfahrzeugbaus", MAN MKE series are referred to have monocoque bodies without chassis. IMHO, the Kassböhrer factory only contributed in building the body (as in case with ÜHIIIs trolleybus, where Uerdingen made the [frameless] body and Henschel - only the transmission components). I suspect the motor power is also wrong, as two sources state MKE 2 had 90 KW/h Siemens motors. This data is accurate and precise. Please correct.

p.s. MKE trolleybuses' length varied: this machine has a longer front overhang than the MKE 3 which worked in Rosario (Argentina).

Cheers!
