Historical stuff

Since nearly a year, I work with different team who do historical reconstitution. My problem is that they work on the same centuries : the XIIIth. Now that  I quite mastered the style of this centuries for belt, bag, scabbard, armor and other accessories, I need clues for others periods.

Of course, I have already some pattern and drawing of leather product across the centuries, like romarian armor, celtic stuff, baldric for musketeers and other things. I even make some of them (I really need to upload the pictures!).

What I am looking for are books. I need books that I can use as a reference. Feel free to submit everything you think worth of interest. Some people ask me for picture and proof that the product tagged "historical" really are historical.

I'm still waiting for answer but I will be able to upload all the daates of festival where I will sell.
