Lot of 7 vintage terminal bases for vacuum tubes, 7-pin & 9-pin

Lot of seven bakelite or hard plastic socket bases for vintage vacuum tubes from the estate of a shortwave radio buff.

There are four 7 pin sockets, 2 in black & 2 in white. They measure about 2" across and 3/4" across the center. There are also 3 9-pin sockets (2 in white and 1 in black) that measure 2 1/8" across and 7/8" across. They all have terminal screws around the edge.
