Anyone ever see a light blue bottomed PB180c?

I think Rockin' Kat mentioned that his PowerBook 180c had a light blue bottom at one point.

EDIT: He said it was because it had been refurbished at one point.

Ya, I've got one. I thought it was painted at first (because I've never heard of that before), until I inspected it more closely and opened it up to discover that it's totally light-blue plastic, exactly identical to the normal grey bottom.

I've heard that it was either a refurbishment thing or an upgrade of some sort, but I've never seen anything official about it.

Strange. Maybe they were trying different types of plastic or something? Pics?

For the record, both of my 180c's (yeah, I do have two, the old "wreck" of one that I've had for years that doesn't work, and has sadly been thrashed like a stolen car, and the good one, which is fully operational, and in showroom condition) have the standard grey bottom case plastics.
