OK, here is an odd question: What does the code "B - OD " mean when it is written on the windshield of a new 4Runner?

I was washing my new 2003 4Runner this afternoon for the first time. While drying off the windshield I noticed a code was once written on there with a grease pen in large letters. Like invisble ink you can only see the letters when running over them with a damp cloth.

I am assuming it was written there during the manufacturing process, but then maybe not. Could be that the shipper or dealer wrote it there.

Aaaanyway, I was curious if anyone knows what these codes mean or what they are about. Very minor mystery, but maybe someone knows the answers.

It usually has to do with the shipping, I think.
