A cam vs. B cam

["Gerardo Magana" <gmagana@softcom.net>]

Hey there, A few people asked how you tell the difference between an "A" and
"B" cam. The answer is that they are stamped on the end, I took a picture of
an "A" cam and posted it on my photopoint album, the link is below for those
of you that are curious.
