They aren’t Bf 109s. They’re Bouchons ... post war Spanish made knockoffs fitted with Merlin engines.
Neat planes in/of themselves, but nowhere near as valuable as authentic Bf 109s are.
The PBY is an interesting bird. It was painted in special commemorative colors in the mid 1980s for the 75th Anniversary of US Naval Aviation and flown across the Atlantic to reenact the first transatlantic flight.
I am still in awe of the quick rate of technology in all areas in a mere 40 years or so leading up to WWII. Nothing else compares, imo.
