    Count the drive links. Usually an even number.
    The saw shop by me makes chain all the time, they want the old chain & count the drive links & make a new chain with that many drive links.
    61 PMMC3 50 ---
    6 = 3/8 pitch
    1 = .043, bar grove width
    P = Picco
    M = micro
    M = mini
    **They just quit using "C" as an identifier on the latest chart.**
    3 = Single-Humped Drive Link
    50 = Drive links

    The "C" used to designate a "Comfort" chain. "C" chains had slightly angled the cutter links to reduce vibration. I think thats universal for all their chain now.

    Manually count the drive links and measure the thickness of your drive links with a cheap veneer caliper. Easiest way to know 100% what you have. Measure drive link thickness at the point between two tie straps.
