I understand that you can't find the stamp size. But since TE has a window die that works with the stamps and they list the size of their die on their website, I was suggesting that you could measure your Madison window die and see if the dimensions are similar between your Madison window die and the TE window die. If the dimensions between the two window dies are similar, then the TE stamp set might work with your Madison window die.
Or you could contact TE and ask them for the dimensions of the stamps.
These are the best suggestions that I have
