  • Sensenich Propeller mystery!!

    Hi,
    I have a Sensenich propeller that is throwing me for a loop. It has the marking on it 42K12335M which I know is supposed to be a 90HA-84 or a 90HA-86. The only problem is Sensenich made these props 90" and my prop tip to tip is exactly 86". also My serial number is 67***(sensenich Bro era I believe) and my drawing number starts with an A (AGDW GNO) which from what I have read is 1932-1942. I think it might have been a Sensenich Bro Fairchild prop, but there is no information on this prop at all! someone wanna help me out!?

    Here is some more information. I hope it helps.
    AGDWGNO
    42K12335M (90ha-86-84, But my prop is 86" long not 90" long)
    SER: 67503 (Strange for this prop?)
    hp:160
    RPM: 1850

    Also the guy I bought it from, bought it from a guy which he also bought a 1918 Jacuzzi propeller, which makes me think this is not a typical Sensenich Prop

      Sounds like the tips may have been shortened.

        So I found out what it is. I called sensenich, and the man I spoke to spoke with his manager (been there for a long time) and the manager said the military had them modify some propellers in the beginning and instead of changing the whole number 42K12335, The military just added the M at the end of 42K12335M to show it was modified. makes a lot more sense. They are trying to find more records on it for me, but he said he didnt know about this before speaking to his manager.
