One of our buddies at another forum found this exceptional example of a unique "CUD" while searching one of his rolls. Interesting reading at CONECA. http://www.conecaonline.org/
HA! I didn't really notice that until now that you mentioned it. I like the sharp edges of the cud itself. Normally they are round.
That's something David has been asking as well. Because it is different from all the other examples, it is unknown. I don't think it is much more than the others but just might be a little higher, I think.
