Bill,
The "WT" on my M/C is VERY lightly stamped. I really had to look hard to see it. I've enclosed a picture for you, and you can see that it's very difficult to make out. I would imagine your "T" is there, but like mine, stamped very lightly. Also, the stamping they used isn't like the normal engine stamps you see. I'm not sure what the font is called, but the closest thing I could find is "Arial Narrow" in my picture editor. My camera doesn't do macro, so this is the best I could get. Perhaps someone else can get you a better picture.
