    Hello All,
    does anyone have a Baldwin service manual that might have specs for whippens and hammer shanks? I am dealing with a customer who had action replace with Renner parts and I don't think the replacement whippets were correct ones for that action stack. An intermediary tech tried to solve problem by both trimming whips 5 mm at drop screw and adjusting action spread north of 115mm or so. To line jack to knuckle core the jack is a good 5mm back(distal?) of reference marks. Whip is 99mm, knuckle is 10mm.
    any help would be much appreciated.
    thanks

    The Baldwin service manual is available on my website as a pdf.

    Hi Fred,
    From the Baldwin Service Manual:
    SD10, SF10 action spread - 4 31/64"
    L, R, M action spread - 4 27/64"

    I hope this helps - it sounds as if you have some action geometry to figure out. Let me know if I can give you any other information.

    All the best,
    Jon
