what kind of socket?

What kind of socket is this? I'm laying out a board but can't find any clues as to what kind of footprint this has.

Do you have the mating plug for this socket? Or are you going to use a 7-pin vacuum tube? I ask because the VHF amplifier I bought used has a socket just like that on the back for controlling the unit. I did not get the factory plug. It is not quite the same as a 7-pin tube socket.
