The time barrel as it came into my shop, the slot on the left is where the tongue for the mainspring was, the hole on the right is part of the previous repair job.
Another view of the time barrel before my repairs.
Previous repair to the time mainspring.
The strike spring before repair, note that the hole is tearing out.
I drilled a hole in the barrel to receive a steel mainspring hook. At the lowewr left is the new hook before installation.
The new hook has been riveted in. I did not smooth off the riveted area, to keep as much metal there as possible for strength.
