Inductors usually have a wide first band, and are packaged in plastic
Of course some old capacitors came that way too.
An ohmmeter will usually do the trick:
Ohms infinite or keep rising with time: A capacitor
Ohms low ( < 1000 ) and keep dropping with time or ohms doesnt match color
code: An inductor.
Ohms > 1000 and steady: Most probably a resistor
Or you can buy a multi-kilobuck LCR bridge.
