Post subject:  Help identifying a part.

There is an individual that is willing to give around 100 propeller parts to the Dixie Wing, of the CAF. The only problem is that we have no idea what aircraft they are for. Here are some pics of the unit; any help would be greatly appreciated. Does any one know where we could sell these?

Hi.

I'm not sure but I've seen similar hub on a German reccy plane. I think it was a small twin boom Focke Wulf, might have been 189.

There should be Part Numbers stamped or etched on the parts along with S/N and possible Mods, ect.
Ham Standard made several basic models with different variation of each.
For example, 24D50-87 is a cuff blade prop for a P-51.
The 24D50 means the prop shaft is a 50 spline.
(The T-6's 1340 is a 40 Spline. Other engines had 50 spline as well, R-2800, Allison V-1710, Wright R-2600. Then there is the 60 spine which C model R-2800, R-3350 and R-4360's had along with C-130 and other Turbo Props.)
The D pertains to the type of Blade used. Common are D, E and F.
The 2 at the beginning pertains to the number of major changes to the propellor. 2,3 and 4 are common.
the 2nd number is the number of blades. 2,3,4.
The dash number identifies the minor changes used in this prop.
R/H turning props are odd numbered and L/H have even dash numbers.
With these props there are a multitude of different setups. The same internal parts with the exception of just a couple different ones are used in a several different props. The hub for a 3 bladed Corsair prop is pretty much the same as a TBM prop. The big difference would be the blades.
What I am driving at is it is important to know part numbers and condition of what this lot of parts contains. Depending on whether a part is rare or used on a popular aircraft and its condition, used/ worn out or NOS will determine its value.
