I'd assume symptoms were caused by some prop seal

I'd probably avoid touching anything and head towards the airport.
Could a prop seal really leak enough oil to make drops appear on the
windscreen? Usually prop seal leaks show up as moisture under the
prop.

We used to have an old diaphragm prop. I invited my teaching attendant
to go flying with us (in his younger years he flew P-51's and then flew
for Phillipine air). About halfway home the diaphragm started to go and
I mentioned it to Ron in the backseat as a way to make sure Jim (flying
in the right seat) didn't get concerned. It took him about 10 seconds
to transition to the instruments (it threw a bunch of oil on the right
side, but the left was ok).
