This original Seeburg lock # 505590 with key is for the 200 selection V3WA and the 160 selection V3W160 wall boxes. 

The lock face has good chrome plating and works well with the key that is included. The retaining pin which attaches it to the locking mechanism is also included.

This is not the correct lock for the 100 selection wall boxes such as the 3W1 or the 3W100.
Those locks operate 90 degrees differently than this lock.
