Dear All,
I recently bought a early wooden propeller made by the firm Hembrug (a firm in Holland), apparently Royal given the crown above the letter W for queen Wilhelmina. The year given is 1918 (see attachment for recontruction of emblem on the propeller).
Furthermore the following information is available on the propeller:
- MODEL HM
- SPOED 170
- 230 PK BEN7
- D 296
Also printed in are:
-N 5 and on the tips on one side 1 and on the other side 2
Could somebody explain to me what BEN7 and N 5 means as well as the function of the 1 and 2 near the tips of the prop?
Furthermore I would be highly interested to know on which aircraft this propeller most likely would have been part of.
