A longtime friend spent his retirement years creating scale models of tractors (Fordsons and others) and implements. There are hundreds of them and the auction is going on now.
For those who remember it, the Model TT with dual rear wheels had belonged to the same gentleman.

Just my opinion -
A collection like that should stay intact and displayed somewhere.
Too bad everything is being sold separately.
Are any of these working models?
