Looks like the 723AB reflex klystrons that I have in my basement.
Mine had been used as local oscillators in 10 GHz radar units.

Looking for information on Marconi SMR-3 and
Northern Electric R8119A receivers.

I think Western Electric made this same type tube for 4 and 6 GHz
as well as 10 GHz. AT&T had equipment that operated in the 10.700
to 12.500 GHz range (Those freq. are close if not exact).
