Upon further recollection, I should update my last post.

The car was actually silver when I saw it, but I knew from the tag that it was originally green.

The last 4 or 5 owners were in Washington, and if any of them had the transmission rebuilt at the local Seattle Muncie guru's shop, they would certainly have been offered the option of "upgrading" to a newly stamped case from his stash of unstamped housings.

This might make more sense, since the Oregon dealer really isn't a "numbers" guy, and I've never heard of him stamping anything else. Doesn't even get that excited about paperwork or documented history. If I ever sold him a car, I think I would zip tie the paperwork to the package tray, since I think otherwise he would stash it in a folder and forget about it, and it may not follow the car.
