[Milsurplus] TCS data plates

[POWERMWT at aol.com]

Gentlemen, I'm looking for the TCS-9 data plates to go along with the 
functioning restoration of my WW2 MB-NAVY-MZ-1 Navy radio jeep. The TCS-9 is listed 
in Willy-Overland's Bill of Materials, basically a detailed list of parts the 
jeep was built with at the factory (the TCS-9 was supplied by the Navy and 
installed by Willys). 

I have three receivers and three transmitters, a mix of TCS-5, 8, 12 and 13, 
I think. 

I have tried to find a TCS-9... one was on ebay some time ago, NOS for $1500 
or so, too rich for me. 

I'm also a newbie at radio and sure would like an explanation on the exact 
differences between the different TCS versions, from the TCS-5 to, say the 
TCS-12. The 13, 14, & 15 seem to obvious physical changes. I have manuals on the 
TCS-5, 12, and 14, just can't seem to see what are the changes in the different 
versions.

Is this change of data plates an acceptable practice? I'm hoping to have my 
jeep judged and they are really strict on using correct data plates for 
restored (Factory) class.  

Regards,
Mark Tombleson
