This is a very rare manual for a type of radio beacon I have never even seen for real. It is basically an improved higher powered version of the PPN-2 Eureka beacon. In the manual you can see what it looked like, how it worked, and how it was used. As you can see in the photos it’s a larger format manual. It is dated 27 December 1944. Very interesting historical reference for paratroop and USAAF collectors.
