Here are a few of my favorites!

There are some large images on some posts, so that might impact your load times, bit I think you will find it worth the wait. Thanks for visiting!

Job Number 170029

Here are some "before" images. It's all old oil and grit. 

Not only is the mainspring in this watch all out of flat, likely form being installed with fingers, but it's the wrong spring. The outer end has tabs and a hole. But this is a motor barrel model.

This is the outer end of the correct mainspring.
Here is the spring installed. The hook in one edge hooks into a slot in the outer half of the motor barrel.

This is an Elgin grade 187, 12 size, 15 jewels, made about 1900.
