  • Unknown propeller

    This propeller is 102.5 inches in length. Stamped on one of the blades:
    DES H(?)561 RII (the H is difficult to read, could be a B)
    NO ?1520 -- ? is indeterminant

    Stamped on the front of hub are the numbers: 358
    The hub is a 8-hole bolt pattern.

    Posting pictures is way too complicated. I can send them in a separate email.
    Thanks, Dwight

    Dwight, you can send the pictures to me by clicking on the small email button below this post then attach the pictures. I'll post them here.

    Is there a name either in decals or stamped into the propeller? Knowing the maker would be a good start.

      Lamar:

      Further clarification of the hub stamping:
      DES. H.561 R.H.
      NO. 11520

      Center hole is 2-11/16 inch diameter
      The eight bolt holes are 5/16 inch diameter

      There is a bit of confusion as to the bolt circle diameter and the hub diameter: I was given three numbers 4-3/8", 5-1/4" and 5-3/8"
