I'm also looking for 1/72 scale GSE and AGE equipment. Hannant's, Shapeways, and F-4 Models as well as AIM and MilMod has some you might be interested in. I'm looking for the B-1 maintenance stand; P-2 Crash Fire Rescue; and O-11A/B Crash Fire Trucks, and all manner of other USAF Vehicles from the 1960's/70's. I worked with one of the Shapeways folks to produce the IH Metro Van. You can find it on Shapeways (3-versions) to paint as FMS, OMS, AMS, and MMS vans from the early 1960 (see Gathering of Eagles for references. Please let me know if you find other vehicles. Oh, also in Shapeways
