Appears to be missing the lever-side contact for the dash contact set.
The lever Pivot ends look okay, they are the rounded style correct for the jeweled movement.
Possible damage to the upper lever pivot jewel. Doesn't look like the lower lever pivot jewel is present in the lower lever pivot jewel screw.

Has sure been beat to hell. Sad. Good "project bug" for rebuilding if one can bid on it and get it for cheap.

It looks like all the pieces are there, including the impossible to find Adjustable Mainspring.
