I have found the image above here: AN/CRN-2 - RadioNerds

For those here who have or have had contact with WWII veterans, was this AN/CR2 system actually used during the war in a practical manner?

Ah, and I have also found something interesting about instrument approaches late in WWII in this link: http://home.att.net/~sallyann2/b29front-page2.htm

According to the first hand account in the link, a B-29 tried to have a ground controlled approach in Iwo Jima while returning from a bombing mission in Japan. Given the content of an article I posted here in the last year (in post 19), about about the CGA development in WWII, I'm not surprise that B-29's were being served by the CGA in the Pacific, given that the system was already finding it's way in the European continent by 1945. Neverthless, it was interesting to have read this.
