Buschbaum?
Yes, here is your next point.
Client from Hanover, body manufacturer and freight forwarder from the Hanover district: This can only go well.
Even before the war, Schaperjahn relied on superstructures from Buschbaum, albeit on a VOMAG basis.
Until the end of Krupp, the Schaperjahn-Krupp-Buschbaum-Bahlsen connection existed, in the end also with double-decker bodies.
When I worked in the Schaperjahn workshop in the early 1980s, most of the fleet came from DAF trucks in the Netherlands.
