Last of a type suggestions?

In the wake of the CAF P-63 incident last week–belly landing after the fuel selector froze–I’m trying to put together a list of FLYING last-of-a-type airplanes. Any suggestions?

These can be absolute last-of-a-type aircraft, like the B-29 Fifi, or they can be last-of-a-mark examples, like the sole Mk XV Seafire flying in the U. S. and the sole Mk XVII Seafire in Europe. Also would like to get as many important civil types as well–not just WWII warbirds.

Replicas don’t count, and I’ll probably end up not including re-engined examples, like Zeros with U. S. engines or Yaks with Allisons…
