I've been on a bit of a HT kick over the last few months, and I'm trying to build up the "hall of armour" from Iron Man 2. I have the Mk II and V suits, as well as outstanding orders for the hall units and the MK I, IV and VII suits.

I've not been able to find any evidence of MK III or VI suits, though. Do these items actually exist, and if so, where am I likely to find them still available?
