Exporting A/C parts from Germany

Hello,
I just bought an older Turboshaft Engine from a seller in Germany.
Apparently German Customs will not let him export it because "The turbine is
used in Military and civil helicopters. Because of the useing in Military
helicopters it is forbidden to export the turbine."

Is he getting a 'run around' or being lied to? Should he arrange to have an
Aviation Parts Supplier or Aircraft Broker ship it to the States?

Suggestions?

Thanks! Larry
