I have photos of the SCR-608, TCS & SCR-300 in USN/USMC radio jeeps. These photos were taken in the summer of 1944 on Guam & Saipan. Oh, the SCR-300 was just setting on the hood. I also have photos of the MAH (RT-19/ARC-4) and what looks like an SCR-510 on top of the TCS offside box on Iwo Jima. Regards, Mark Tombleson
