Thanks, Gene: I'll forward them tomorrow when I get to the office; however, I guess my stupidity will show! Wiped the air cleaner down to take the pictures, and discovered a "Sprint" decal on it - faded and partially missing, but clear enough! This one, however, has no air horn, so sometime this week I'll pull it off and try to determine what that is all about. I ran my hand around the top, and could not feel a place for one - but there must be some way for air to get inside......the mystery (to me!) continues!
