Elgin Grade 293, And A Creative Mainspring Repair

This mainspring is no good, it's way out of flat. This sort of thing is usually the result of installing spring without using a correct winder.

But this spring has another surprise!

A break has had a make-shift repaired with a little buckle of sorts. That's a new on me...

The watch is a grade 293 Elgin, 16 size, 7 jewels, made about 1917.
