Just got these shined up yesterday. They're brass shells, 10.5 and like 13.3 inches. They came with the original calf heads, which are in fine playable condition. I've always wanted a drum with the Gladstone-style split brackets, now I have to track down a cymbal arm.
They sound really cool, but I'm not so into calf heads so I'll probably eventually send these to Remo and have them make some custom-sized Ambassadors for them.
