Here is a table that describes all the differences of the Louis XIII bottles that have been produced in the past up till now. To illustrate some of the major changes I put up some pictures thact you can click. Through the years the packaging of the bottles also changed a lot, but I have not gone into that. If you like you can check this out on a page that helped me a lot, but it looks like this page is not maintained anymore: here.
