Default Identify an old prop

DES is a desination used by Flottorp pre 1944. The Flottorp 90" prop was made in 54 to 70 pitch and the thickness of the hub was only 4". They were made with 5 laminations of birch and were tipped with either stainless steel or copper. The bore was standard at 2 11/16" and had eight 3/8"bolts on a 5 1/4" bolt circle, but this could vary between engines. Measure these and see if it matches.
Daves right. A couple of pictures would really help. Also see if there is any remains of a decal left on the prop blade. Even an outline of a decal could help identify it.
