  1. Hello Darrel,

    This part is very common and should not cost much.
    It’s about 5 U.S. dollars.
    It’s a “suspension spring.”

    They come in different sizes.

    They are made flimsy so they can break easy.

    “Suspension springs” can be found here.

    It is held by a “taper pin.”

    Simply pull on the thicker end of the taper pin and pull it out.
    Be careful not to bend the suspension bracket.
    The suspension spring will slide right out.
    Just replace it and you are back in business.

    Timesavers and Merritt’s Antiques sells Suspension Springs and taper pins in the U.S.A. I’m sorry I do not know of any U.K. horological suppliers.
