I guess I don't see enough difference to make it a different code in the Seymour book, but maybe someone else can verify it one way or the other.

Quite a few chips are shown with variations but they are given the same code.

Try this web site and locate the PA-TZ:

This was what I was questioning in my original post. They look very different to me but the book gives them the same code.

There is also a PA-UC that is very similar to the PA-TZ without the whiskers on the top. It's all very confusing to me

If you find out any thing new about them, please email me.

I'm going to LV tomorrow (Really, really big grin) and if I don't pack soon, I'm going to be either thrown out of the convention or really popular!!!!
