Bumblebee caps are in molded black plastic cases and the values are colore coded on them like resistors (some are much bigger than any color coded resistor which is a visual give away). I believe that "big Chiefs" are molded plastic as well but do not have the color code stripes. Plastic Molded paper capacitors come in many colors and trade names and are easy to spot once you know what they generaly look like (or by tracing the schematic if you are good at doing so).

I wish I had time to snap some photos of some bumblebees, and other types I've replaced to show you, but I'm sure the other will do that soon.
