This Bird 72-2, 2 Position, 2 Circuit  50-Ohm Coaxial Selector Switch, is in Excellent Condition.

It does not have the position plate but I believe they are available from Bird.

  This Coax switch is still in production and currently retails for $2193.00

You can find then on the used market for less but many are in poor condition.

 This one looks and works great on frequencies from DC to 10 GHz.

72-2, 2 Position - 2 Circuit

Coaxwitch, RF Coaxial Selector Switch

Bird®, 50-Ohm Coaxial Selector Switches employ a unique, rugged and reliable design which permits positive contact, low insertion VSWR and negligible cross talk between channels. The switching mechanism is 4 1/2" of RG-87/U Teflon cable which is pulled away from the mating Male N connectors and rotated to the desired switch position.

The switches have a valuable advantage that they cannot be operated accidentally, but must be operated by intentional sequential movement. The knob must be grasped, pulled out, rotated and pushed in to make contact.
