Hi Ralph,
I have the actual radio and the service manual about it for a 1948 Stinson.
The radio is a Hallicraftafters Skyphone CA-2. It was not originally in the
Stinson my wife and I owned. I wish I still had the Stinson 9308K but it is
currently in Alaska. It was stolen from Mt. Hawley Airport in Peoria,
Illinois when my wife and I owned it. It was found near Red Wing Minnesota
before we knew it was gone. Someone took it somewhere around 4:00 Am from
Mt. Hawley airport in Peoria and made a dead stick landing near Red Wing
about 07:00 am. He got a ride into town and went to the local bar for a ??
After awhile he said well I better get back to my airplane and walked out
the door. His finger prints were all over the Stinson but after comparing
them to mine and my wife's they never showed up in any of the Feds files.
Since an airplane is a Federally registered vehicle if one is stolen the FBI
gets involved. Well they didn't give a rat's ass about who took it but where
concerned about why they wanted to leave the Peoria area so quick or why
they wanted to get to the Twin Cities so fast. The only hope my wife and I
have is some sucker on his death bed will go" do you know what I took from
Mt. Hawley Airport in the past?? It was a great airplane and my wife was the
only one that went for a ride in a bean field with it duringa ground loop!
Sorry to digress from the topic at hand but if you ever need a manual for a
CA-2 or a CA-4 let me know!

Would like to get references to early use of airborne radio equipment Pre
1950. Are there any museums dedicated to this?

Thanks
