    The two larger resistors were pulled from a Hammond chord organ. (The small one is a 1/2 Watt for scale. )

    Should assume they're rated at 1 watt?

    They're 15 mm by 6 mm in diameter.

    I have to look at a resistor chart to check mine.

    as far as what wattage they are I have no idea.

    Likely one watt.

    Yep, for that era/type, 1W for sure! Now the question is what is measured resistance for these pulls...

    Pulling resistors? I only use carbon comps for repair work if the customer insists. Anything old has either had 50 years worth of current run through it, been exposed to tons of moisture, or both.

    If you need to know the wattage because you're replacing them, those look like 1W to me for sure. A modern 1W would likely be the same size or smaller than the small one you have as your example.

    These are for my own builds. I am a scavenger, and I'm happily making stuff using things that are headed for the landfill.

    I test them prior to using them, and I only use stuff that came out of Chord organs that sat in someone's living room for 50 years. No rusty dirty chassis.

    How much use do you think the average chord organ got? Those things are like modern home exercise machines. Rarely used after the first year.
    People bought them for Christmas, and they used them for decoration for half a century.

    My mom has a piano in her living room because "it is a beautiful piece of furniture!" It hasn't been played in fifty years.
