Which is the Table about Model WT when I copy some WT´s

Hi my dear friends:

I have a doubt, does anybody can help me to know which is the table where I can see the WT´s copied and which is the Model WT for that WT´s copied?

Or How can I know which is the WT Model (Origin) of a WT copied previously?

Thanks in advance for your precious help.

Best Regards to all.
