How can anyone help you when we do not know what mark look’s like? We also need to see many pictures of your pitcher Can you post pictures on photobucket or some other sites? I have repeatedly ask this site for more help on posting pictures, a lot of people are having a lot of trouble. This is a good site for novices but it would be nice to see the owners make it a freindlier site to use. If your pitcher has a mark can you discribe it?
