WOW, nice find, you probably know that the HEM museum has the only surviving SCR-270 array.
well guess what theres another chasis here in denver. actually its for sale in supply line. but its missing its box also.
dont know if its a K-30, K-31, or K-62,, I think its a 43, wich makes me think its a K-62 but who knows.
theres some good pics on the fort gorden website.
