I've been doing some research for a pair of future IDF builds:
1) A modern day Macha"g (Academy M579 fitter with the Legend Chata"p)
2) An early M113 Chata"p (Tamiya M113 with the Verlinden Command Vehicle/Technical Team conversion, #312) circa the mid 1980s
I picked up the Desert Eagle Zelda M113, part 1, Fitters book. It's a fantastic reference especially if you're doing a more modern fitter.
Unfortunately, I haven't had much success finding "in action" photos of the early technical vehicles. Page 12 of the Desert Eagle book has three photos of early M113 Chata"ps. Two are of the same vehicle, the third may be as well but it is hard to make out the serial number. (I'd also love to know when and where they were taken)
Oddly enough, the Verlinden set has sketches of the two sides of the M113s, as shown in the Desert Eagle book, as possible configurations. Given that the Verlinden set came out in the Mid to Late 1980s, these photos had to exist elsewhere.
Many of the Verlinden sets and dry transfers of that era can be traced back to Osprey and Squadron publications as their source material but I haven't been able to locate anything (in print or online) on these or other early IDF repair vehicles.
Maybe I'm not punching in the right combinations of key words into google. If anyone has any leads, photos or links for M113 fitters/Chata"ps/technical/repair vehicles or whatever you want to call them, circa the 1980s, I'd appreciate it.
