Help Me ID this 8 Bolt Prop

[colonelak]

Attached are some photos of a prop that I purchased about ten years ago at a flea market. Unfortunately, it already came with a clock inserted on one side and it is fairly scratched up. Still, I think it is really beautiful and would like to clean it up a bit and mount it. I'd love to find out what plane it was from first. I've tried to ID it based on the suggestions available on this site and others and haven't had much luck. The props that I have seen posted that most resemble it are from Sensenich. Anyway, here are the measurements:
8 Bolts
Approx 90 inches long
Marking in the middle: DWGNO1
Serial No. 25859 (Note this appears on top of the hub and on one side of it - the side without the clock)

There is also a small letter K in the middle, seemingly in a random spot. I have seen somewhere on the site that this may indicate military but am not sure.

I would love any input and can take better pictures of a particular angle, if requested.

Thanks!

Tough task. It looks as if the numbers were there but are no longer legible.

I think the best you can do is go to this page and see which models may come closest to what you have on yours.

Thanks Dave. I did try that but couldn't find a match. The Serial # is clear as day, along with the "DWGNO1" - which is frustrating. Do you have any idea whether it's likely to be an "early" prop, just based on the pics and the size/bold configuration?

Anyone else?? Any help would be really appreciated.

My guess, based on the size and geometric shape is that it's a more "modern" propeller, likely from the 40's, 50's or so. That's the period of time when metal sheathed, straight blade, higher rpm props were common, and this certainly appears to fit in that category.

Thanks Dave. What do you think about it being from a Stearman? http://www.flickr.com/photos/johninm...6691/lightbox/

Looks like a close match. The atypical characteristics of your prop are the massive bulk of the hub area compared with the comparatively short span of the prop. It's unusual in my experience, which I hasten to add is of European props.

Well, it could be from a Stearman, but it's not unlike a tire. It may look the same but be completely different. Without the drawing numbers it's almost always going to be a guess.

If you can get accurate hub measurements I could check those against known measurements for a Stearman.

I will get you the measurements tonight. I was looking around and found another prop that seems very similar, this from a British plane http://www.onlineauction.com/index.p...ion_id=1284174, at least according to the poster, a Cheetah Avro Anson.


Thanks a lot gents.

There are certainly lots of those around, from various manufacturers. I think they were produced in huge supply and then variable pitch metal props took over, creating a huge surplus of worthless wooden ones.
