Today, Saturday 21 MAY2022, at 1630LT, I saw what looked like a P.149 in a light blueish livery flying low altitude over the river Maas near the town of Maren, heading northeast. It looked a bit like OY-POT, but it didn't seem to have a big Danish flag on its tail fin. Unfortunately, it didn't show on adsb.
Can anyone help, because I have a bit of hope it is an ex-German military P.149D.
