I just stumbled upon this magnificently preserved Grumman G-73 Mallard, J34:

Like the Cat there are around thirty-ish of these still airworthy, and unlike the Cat some were converted to turboprop, and this is one of them. First flight in 1948! It even flew around the world a couple of times… Its history is fascinating, you can read it at Mallard Aviation.
The range is shortish and I still prefer the Cat 
but that’s a damn fine piece of aircraft if I ever saw one. Beautiful! I wonder how much they ask for it…
