    Can you not measure it with an ohmmeter?

    That's a bit tricky when the resistance varies according to temperature.

    I've found the answer anyway, R - 15k ohm (-/+ 5%), B - 3470K.

    Thanks for the help (and yeh I used the pdf from Vishay)

    Thermistors are usually declared by their resistance at 25 degrees C.
    It shouldn't be awfully hard to get them close to that temperature. Measuring them with a wire broken off is a different problem!

    Yeah those old one-legged style parts are hard to measure for ohms. ;)
