View Full Version : Yet another wayward propeller owner!

Hello folks! My father recently dragged out an old propeller we've had banging around in the family for years, and we decided to get started on identifying the thing.

So far, utilizing this website, we've been able to figure that it's likely an early prop, given the eight bolt holes and the low RPM of 1470.

We managed to get a few numbers off of it, but a lot of them were pretty chowdered up, so we can't be 100% sure-- here's what we've got:

Part No. 845R

BAP No. 7818.... Or 7848, or maybe even 7813? This was one of the bugger numbers that wound up with a few scars here and there.

Aaaand that's about all we've got for now.

Not much to go on there, especially when the numbers themselves are near illegible.

"BAP" stands for "Bureau of Aircraft Production", so it dates some time after 1918 (https://en.wikipedia.org/wiki/Division_of_Military_Aeronautics).
