Really nice collection, I am new to this so only have about 16 G's. I would love to one day be able to have something like you have. Being able to wheel and deal with your collection in order to get choice pieces is awesome! I especially love the green and orange Muddie, I have seen that one on the bay but still out of my price range.
I like the cases as well, keeps them all nice and tidy. All mine are still in their respective boxes in a drawer in my room until I move into our new house where they will be displayed. For me, displaying the box, tin and watch is all part of it so I have already claimed some space in my wifes curio cabinet which matches the rest of our furniture and has glass on three sides with a mirror on the back and a light on top. We'll see how that all works out.
Anyway, I'll be looking forward to see how your collection evolves.
