I'm sure this has been asked and answered a dozen times... but...
Now that the Great Unpacking is fin-huh-leeeee underway, I hit a vein of hot rods in one of the boxes and dang if there weren't a pair of the Mk. 1 Mod. 0 '30s in there.
I'd pull 'em out to A/B, but I will never get anywhwere with several hundred to go, so I'm cheating a bit here by summoning the board's knowlege.
Any help from the experts is much appreciated!
