Help With Prop ID

Jim Lessig · 03-18-2017, 07:58 PM

Hey guys, I found this wooden propeller in a creek next to my house today. I thought it was an old lawn mower blade at first and was going to scrap it, but when I picked it up I realized what it was. Looks old, but I have no clue what era it's from. I was hoping someone could help me ID it. The only markings I can see on it I think say "54-56-52". I've attached a photo of the markings because they're not that legible. The prop is exactly 54.5" long. I'm not quite sure, but it looks to be a left hand rotation prop.

Just a guess, but I think it's an ultralight propeller. It's too short for a typical certificated aircraft, even one with a smaller engine.

That makes sense. I just found these props for gyros. http://www.tn-prop.com/Propellers.html I think the second and the last ones look the closest to what I have. Pretty cool find, especially laying in the brackish water creek next to my house. I just wonder if it was lost by someone or if it was a crash. My house sits at the very top of Tampa Bay in FL. It's about 1000 yards of marsh and mangroves between me and the bay. Not sure if there's a way to tell what year it was made, but it's definitely been in there for a while.
