The Fort MacArthur Museum is owned and operated by the City of Los Angeles, and is open weekends and limited hours weekdays. They have a great collection of vintage military communications and radio equipment too.
Now for the best part: We got there a bit late; about 30 minutes before closing time. But I happened to catch Joe, the head person. After chatting for a minute, and showing genuine interest, he invited us behind the scenes after the museum closed! I got a private tour of two of the restoration shops!!!!! What a privilege! Dad took the top photo of my expression (from the back) when I stepped in the door and looked up
The sirens shown on the pallets are fully restored and waiting for a place to display. They don't want to put them outside because they would look like the SD10 in the bottom photo pretty quickly in that corrosive ocean air. 
Here is an unrestored (VERY VERY VERY unrestored) SD10 out front of the battery at the museum:
Joe and I discussed the prospect of getting hold of, and restoring, a Chrysler. Turns out he and I were #1 and #2 bidders on the eBay one earlier this year 8) Maybe someday....
BOTTOM LINE: I encourage anyone here with a true interest in this stuff to go there. Be nice to Joe, and you might get in the back rooms!
