Hello:
My bet would be the Hetzer that is up at CFB Borden (it's a very early production example). There was a restoration to running condition that was started on that vehicle 10 years or so ago, but with the passing away of the project coordinator (a German WWII vet), the vehicle was reassembled and put back on outdoor display several years ago.
Here are some photos of the vehicle when it was under restoration:

I wish they had the Wirbelwind from Borden (I think), but the Hetzer is a lot more manageable. So is the Grizzly Firefly project complete?
Cheers,
Scott
