Incidentally, there was a sticker that was affixed to the bottom of the orginal hood tach's that said, "DO NOT EXCEED 180 IN PAINTING" that has been reproduced by In-Line Tube. The sticker should have a "degree" mark after "180" but that detail was omitted from the repo, but it can be added with a small black marker. The sticker goes where the stickers are on the bottom of the above tach.
