Duly noted. Thanks for that clarification.

Bogus refers to the general claims that they were linked to something or someone of historical significance, not to the identification of the propeller itself.

Not sure about the “bogus” label but the way mine is stamped suggests it is real as well as we live in an area where there were several BCATP airstrips. The fellow who gave it to me around’86 was a LONG-retired wwII RCAF officer.

I also have a hartzell propellar a clock is mounted in the center we have had it hanging for years, my husbands boss gave it to him around 1986 and said it belonged to Howard Hughes as his boss was a world traveler and has since passed away. I was curious how i would be sure of that????? Any ideas????

The folklore that goes along with many of these props (and maybe ALL of them) is almost always bogus. Unless it can be substantiated with convincing evidence, then it's just that - folklore. The problem of course is that once people believe it to be true, it's very hard to reverse that belief, even when there's convincing evidence that the connection can't even possibly be true.

Hartzell Prop

Thanks very much Lamar. Again, the website is outstanding. I had NO idea there was so much to the subject or so much interest in props and spent darn near a whole day (when I should have been doing other things) perusing the site and enjoyed every minute. I was struck by the shear number of wooden props out there. Cheers.

On the one hand, this website says the 8 hole design makes it pre 1920

Let me attempt to clear up a little confusion here. I suspect what you read said something to the effect that pre-1920's props were almost always 8 bolt holes rather than 6. This does NOT mean that props with 8 bolt holes stopped in the 20's. They persist to this day. The number of bolt holes has to do with the diameter of the prop which itself relates to the RPM's of the engine and other factors.

You read the chart correctly. Your prop seems to be for either of those two aircraft.

I'm trying to research my wooden prop and getting conflicting info. On the one hand, this website says the 8 hole design makes it pre 1920 but some onfo on http://www.modernwoodenpropellers.com/hartzell.htm indicates its from a Beech B17 or Cessna T-50 ca 1940.
Markings are: Hartzell Decals (It's 90 1/4" long, Hub 6" thick)

Design 707 80 (SU)
SR NO 26759
RPM 2000

Hartzell A.T.NO.
Piqua Ohio 457
HP 225
I would like to frame a picture of the correct airplane it was used for so would appreciate any further information you could supply. Thanks.
PS Love your website!
