Always been interested in this corsair for various reasons. I stumbled across this site that indicates it is not really a birdcage unit. I had not read about this modification before but after looking at the pics in the yard in Provo again it would seem he is correct.
So that would make the one from Lake Michigan the only survivor except for perhaps the uber double secret private unit in California?
Any idea of the Bu. No. of the one in the swamp here in FL?
