View Full Version : Propeller ID Question

02-15-2018, 07:07 PM
Hi forum members! I'm relatively new to the propeller world and looking for information on this propeller. Any information on a possible maker would be excellent, as I couldn't pair it with an identified propeller on the host website.
Looks to have had 8 holes originally, with 128"L and 11"hub. Marked "WP-X4987" and "613" on the other side. Probably walnut or cherry? Thank you!

It's a nice looking prop, and its size and shape suggests a late teens usage. I'm going to try to dig through some old files to see if I can make sense of the markings. Sometimes the "X" indicates experimental although often not the case.

If you can upload the full file version of the photos it might help. Also, even though some extra holes have been drilled and the original holes may have been enlarged or elongated, see if you can eliminate some engine applications using this link (http://www.woodenpropeller.com/Hubmeasure.html). My guess is that it's consistent with a Liberty engine.
