Hamilton WW2 Ship Chronometer Spring Detent Locking Jewel WEDGE

This is wedge that is used to help hold and orient the locking jewel in the spring detent assembly.  It is a half-cylinder and is very small.  The second picture is the spring detent for a Hamilton model 21 movement. The model 21 is the large spring detent escapement chronometer shown in the third picture. No locking jewel.
