I have been studying NAVSHIPS 900,109 since I was made aware of it back in October, Farrell.
Do you have a copy of Volume 2 where I write about the radio jeeps?
CVD 10182 = Navy MZ = Willys model NOM-12 for example is only partially true as the NOM-12 came from the factory without radio and could be had with the SCR-608. Same for the MZ-2... I even included this MZ-2 data plate showing the SCR-608 in my chapter in Lloyd's book.
NAVSHIPS 900,109 gives the name and description of the radio jeeps but it does not match up entirely with other documentation and physical evidence. I was talking to Fred at length today and it will take some time to figure this out.
We have a group of contracts, a group of BOMs, NAVSHIPS 900,109, Data Plates, letters and support documentation that doesn't reinforce each other in all cases. An example of this is NAVSHIPS 900,109 seems to indicate the MZ-1 is the CVD-10182-A, if so why is the A not on the data plate similar to the other data plates. Why does NAVSHIPS 900,109 not show the SCR-608 for the MZ-2 as shown on that data plate. Another issue is the detail items... like the antenna box shown in the MZ-2 Supplement is the earlier A-4864 box (with 12 cover screws) and the BOM shows A-12443 box (with 11 cover screws).
Some contracts are just on a plate or note in a BOM... viewtopic.php?p=762027
We may need to start separate threads on each model/contract or CVD type .
