  • Propeller ID #2

    This propeller has a decal which reads Matthew Bros Mfg Co, Milwakee Wis. USA. around the edge and Hamilton in center.
    Stamped on prop is Matthew Bros MFG Co. , N-12172, 8" 4", SE 5090, HS-2. Measurements are as follows:
    center bore diameter- 3 3/16"
    Bolt hole circle-8"
    diameter of hub- 10"
    number of bolts-8
    bolt hole diameter -1/2"
    hub diameter-3 5/8"
    Think it might have been off a M F Boat with a Curtiss OXX 6 engine???
    Any ideas?

    It's for a Curtiss HS2L flying boat with a Liberty engine. See http://www.woodenpropeller.com/Curtiss_HS2L.html for a further description.
