Thank you to everyone who commented on the vehicle photo on the HVA website and the HVA's Facebook page.
The vehicle in the photo is a 1952-53 IFA Framo V 901 Kosterwagen.
The FRAMO marque was produced in Saxony by the Frankenberg Motorenwerke, which produced vehicles either side of World War II, until production was switched to Chemnitz (Karl-Marx-Stadt) under the name Barkas which was the East German manufacturer of small delivery vans and minibuses named B1000.
And the winner of the contest – Scott Windle from Upper Dublin, PA!
For guessing correctly Scott Windle will receive a free HVA ballcap.
