    That sounds about right. You can verify by measuring the pallet fork slot and subtracting 0.02mm.

    I don't know. I went to the pocket watch web site and it doesn't say and I'm not sure how to tell. Terry

    BCMC,
    I had answered your question the first time you posted about it. Was there some problem with the advise or help that I gave you?
