I had some of the dual 3 input parts used in the AGC block2 and still have 
a few uA709 opamps in the 8leg flavor.  Package actually was flat ceramic 
hermetic and lived formany years for mil, High rel, and extended temp 
appications for a cost premium.  Look in Burr brown, Intersil, or old RCA
data books before 1976 and you may see samples of the package.
