  • propeller info needed please no pics yet

    i have a propeller with the stamping on it as follows:

    Airship OB-1
    Part No.066422
    A.C. No.28-2800

    with the measurements of hub thickness 4 1/2"
    hub diameter no metal 5 3/4"
    Center bore 2 5/8"
    bolt size 3/8"
    bolt circle 4 1/2"

    if you know of a web site where i can research it myself or any help would be great

    Does it by any chance look like this propeller? I can measure the hub dimensions later, but this is one of the few props that used the Lawrance engine.

      prop with no pics again

      it is a lawence but it does not look like the one you have in that photo dave it has a rounder cut edge in stead of the point on it it is a dark color wood and has a round cutting edge with a half moon type design on it 7 of them then on the end it has a straight line in off the edge about 4" i cant take a good enough picture of it to show you it is all one piece design on it . also right know there is a pic of a prop on top of this forum that has the general shape of the prop i have but no gray on it ... i'll try to get some more pics tonight but not having luck on good ones which shows details any ideas ?
