Thanks. It was a lucky find. Hard to believe the Army kept one in use (all be it not much use) for 55 years. I did buy an M109 for parts because I thought the van bodies were all the same, but I discovered the black out window mullions were different extrusions. At first blush, things look the same. I am missing one of the shades and the bottom piece of mullion for that shade. Also there are slight differences to the window tilt out rods and I need a couple of those repaired. I think when I get some time I can fabricate the repair parts for the prop rods. Anyhow, I have an M109 parts truck that the military did not strip parts off of the van body. The rest of the truck did get ravaged for spares though. ~~~ As to your search for an M220, I would check the GSA auctions and if possible small fire and sheriff departments. Two years back, I ran across an M220 out in Eastern Colorado, but I was a few days late. I heard about it from a near by rural fire department. By the time I tracked down phone numbers and made contact, it had gone to the shredder the week earlier.
