Shape looked familiar, was thinking VDM from either 109G or Fw 190, so checked the net:

VDM 9-12153 A, 3.3 m circumference; one of 3 props authorised by BMW for Fw 190A/F/G series aircraft. Same prop as VDM 9-12067 A, difference being the external weights.
 
Certainly looks like a late '109 blade, but not sure about those flanges, weights or whatever. Balance weights were normally disc-like, but of course there are/were variations.
 
Good info Sander. Yes, the weights are for balancing the prop blade, and can be seen clearly on some props which don't have a spinner covering the hub. They are often in the form of a disc, rather like an ice-hockey puk, and are known as 'bob weights'.
 
Thanks Gentlemen for your interest. So those "weights" were used as counterweights if one prop blade has less weight than the other two, right?
I wonder if there is any manual about VDM that shows all different types of prop blades. What's the difference between VDM 9-12153 A and VDM 9-12067 A?
 
Just a guess, but I would think the weights would also put the prop in low pitch should the prop fail in flight.

According to that net info I posted, the weights.
