Job Number 180070

This one is a grade 10 Elgin, 18 size, 11 jewels, made about 1893. 

This lever is part of the setting mechanism. On the left of the part is a post that carries a gear underneath. The post is threaded in, but seems to get striped somehow. Sometimes they are loose, and sometimes missing.

This one must not have been staying in place as some prior repairer has places a series of divots with a punch, all around the part.

See more "creative repairs" here.

The serial number prefix, used on stamps on all the major parts, is a small 't'.
