That's a nice looking pair. I'm glad you're digging it. I would assume the radius is 7.25* which I love for chords, though they can be a little challenging for lead. Hope it works out for you.
I'd shoot some Deoxit/tuner cleaner down the shaft of that tone pot and see if the static goes away. My Bluesbird's pots were noisy when I got it—I suspect the guitar hadn't been played much by its previous owner—but the Deoxit plus working the pots back & forth took care of the issue. At least you'll find out whether you're dealing with corrosion/oxidation or wear.
