Electronics Plastic housing

I have a plastic housing for a VCR with some molded-in markings on the inside. *There is a circle with an arrow inside and two numbers outside. "1207" & "1208" The arrow is pointing to "1207" *There is a circle with an arrow inside and the numbers 0-9 on the outside. The arrow is pointing to "4" *There is a circle with an arrow inside and the numbers 0-3 on the outside. The arrow is pointing to "0" *There is a circle with an arrow inside and the letters A-H on the outside. The arrow is pointing to "B" *There are also two charts that has letters on the left and what looks like names of pigment colors on the right column. Some of the right side fields are blank. *There is another chart with "00", "99", and "98" on the y-axis and the numbers 1-9, 0, and the letters "N" and "D" on the x-axis. There are two markings - one at the intersection of "99" and "1" and another at "99" and "2". Does anybody know what these markings mean? I've seen similar markings on other bits of plastic electronic housing. I imagine that they explain the material that the housing is made of , but what do they mean? Anybody know? Have any ideas?

By the way, you could also hit the "edit topic" link in the green "Author options" box, and attach those pictures directly to the topic at the top.

I was hoping that there was some kind of way to know what plastic it is made of.

That's exactly the link Linux gave you. Look for a number inside a recycling triangle, and follow the charts provided from Linux's link.

Tried that. Failed to find triangle. Still would like to know what the symbols mean.

Unfortunately, if the box doesn't have the "recycle" symbol, I don't think you're going to find out what it's made of. Generally speaking, the rigid plastic boxes are polycarbonate (think iBook). Most of the symbols you described above (circles with arrows) are used by the factories to identify things like production dates, batch numbers, factory locations and the like. If you know the manufacturer, you might be able to get a Google search to come up with a factory manual specifying those codes. Being successful with that will require some experimenting, tweaking the terms you put in, probably adding "-XXXX" vetoes as you see results that are not useful to you.
