Fw 190 Propeller Pitch Balance Weights?

[razor1uk]

I wonder if there was, or it is known of there being any externally mounted (outside of the spinner) pitch balance weights/counterweights towards the base of each blade on some 190's depending on model/engine spec/supply problems etc.

Any help would be useful, especially if with pics, manuals or info supporting or denying said pitch weights.

Thanks in advance
