    Is this a Harley R series shift drum?

    Good morning,
    I would appreciate help identifying this shift drum. It looks similar to Harley R series, but look at the pictures and compare them to Harley because they are different. I do not know what it fits.
    The overall length is 2.510" , overall diameter is 2.245" , the round hole is .625" and square hole is .437", the slots are .315" average.
    Thank you,

    The pictures are an early #2243-33 shifting cam, it will work with any '33-'37 reverse and '35-'37 solo 45 tranny.
    There were three versions of this part, but the part nos. never changed.
    Also, there were 2 versions of the #2235-33 gear shifter shaft.
    The later parts were improvements providing better access to gear shifter shaft nut and lock washer with larger shifter cam and shaft mating surfaces.

    Thank you for your reply. I have had the part for many years and could not recall if I ever tried to fit it in a transmission.
    I appreciate your time.
    Thank you,
