Here's a quick list of vehicles and locations that I already know of:
Barbers Point Naval Air Museum: M60A3 x 2; M901; M110A2; M578; misc soft-skins.
Tropic Lightning Museum at Schofield Barracks: M4A3(76)HVSS; M59 APC; M114 155mm howitzer; 105mm howitzer (not sure if M101 or M102); M167 towed Vulcan.
Ft DeRussy: M24 Chaffee; Type 95 Ha-Go; misc items
Pacific Aviation Museum on Ford Island has several soft-skins.
If there are any others to be found, I'm sure I'll track them down as I'll be there for a couple of weeks. As I just picked up a new laptop, I should be able to post some pics while I'm there, at least that is the plan.
