1. Can you obtain air pumpe sold in Switzerland by "REX Die gute Schweizer Pumpe La bonne pompe suisse". This is the same pumpe used on pre and early post war BMW. It may only be available in a military green... ?swiss army. 2. What does the mark +GF+ found on the undersurface of the upper fork plate of plunger BMW twins mean? Is this item cast forBMW in Switzerland? Does the + represent the Swiss cross? 3. Can anyone in Switzerland give me production year of Universal shaft drive opposed twin B50 #170827. This is a Universal, not a Rabenick

Salü Stephan!
I can only help you with a German made pump for the prewar machines.
The +GF+ on many BMW castings is the company logo of "Georg Fischer" in Schaffhausen who made many castings for BMW before, during and after the war. You might find the same logo on your water taps and plumbing junctions in your cellar at home.

The Universal expect in Switzerland is Willy Janssen,
