I just put this up on ebay, starting price $50:
----------------------------------------------
Boonton Model 59 grid dip oscillator S/N 4128, manufactured 1947. Includes
original set of 7 coils and manual. Surplus from a university lab. Hasn't
been used for years. Looks clean and complete except line cord is cracked
and should be replaced. Supplied as is.

Lots of descriptive information is available on the web for this particular
unit.
