Hi David, 
I would love to purchase a copy of the radio airchecks. What method of payment is best for you? I'm in the USA so modify shipping accordingly. 
Thanks for sharing these cool recordings.

I listed them on Facebook groups but keep forgetting there are luddites over here, so drop me a request for the list if you're interested. $20 +$5 shipping. (In Canada, we'll accept beaver pelts.)
