Opa seiner – Grandpa’s one

The service division of SKS GERMANY sometimes achieves quite curious requests. So technician Winfried Geuecke got in 2013 a RENNKOMPRESSOR of the first generation for repairing. A dealer from NRW/Germany wanted to make sure that he really gets his pump back and so annotated the pump pipe with the writing »Opa seiner« (Grandpa’s one)
