The OPs old polarizer would be this kind. You put it on the camera and rotate it to get the desired effect.
Yes it is. It even has a handle for rotating it.

This is not correct. A linear Polarizer (usually a type PL) is a glass element that rotates on a glassless base, rotated to block the reflections from a certain direction.
I agree, what I meant was that in a CPL you rotate the two elements to get the desired affect with one element staying still and the other moving but with a linear you rotate the single element to get the desired affect. Linear polarizers usually have a notched edge to allow them to be turned or sometimes a lever. But my intent certainly did not come out correctly in that post. Sorry if I confused anyone.

You might also be missing modern coatings that are present on the nicer filters available today from Hoya, etc. These coatings will help stop reflections from filter elements. I think some of the Hoya ones feature SMC even. However, depending on the lens, that really won't hurt you too much.
