Elgin Grade 293, and End-Shake Adjustment

Here's something I see a lot of...

There are divots raised with a graver under the balance cock to make the thing sit higher and increase the end-shake.  Sometimes I see them added, filed off, and added again.  After awhile it's extremely difficult to get the parts to seat correctly.

This is almost always a "fix" done to avoid something slightly harder, or requiring parts or tools that were not available, like changing the balance staff or the jewels.

This movement is a grade 293, Elgin, 16 size, 7 jewels, made about 1920.
