    This is from a French crystal regulator. Guess that's why it had trouble running...

    I think 8 pieces of spring is a record for me.

    *Edit* Make that 10 pieces, found two more on the floor.

    A spring in a barrel, that breaks when nearly fully wound, goes through a chain reaction that cascades like dominoes. We've seen some examples here over the years that had dozens of pieces as a result. It's a little odd though that both your innermost coil and outermost coil broke.

    Probably one broke as a consequence to the shock that happened when the other broke.

    Someone has the record at around 80 pieces.

    You will probably need to replace that one ... :)

    Maybe rivet all the pieces together?

    It seems that the clock has once been cleaned with the complete barrel/spring assembly submerged in aqueous cleaning solution. There's a lot of rust. Probably that contributed to the catastrophic failure.

    A broken mainspring in a wind-up phonograph will yield a barrel filled with a pudding that consists of 50% graphite grease and 50% half-inch-long pieces of 1" wide spring. I have these tinkling all over the basement floor to this day. These machines have two mainsprings, each in its own barrel, and only one broke. There was no further damage.

    I had a 400-day shattered mainspring once, but I think that was all.
