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.
