I just got a book a few days ago that I bought on the us ebay ,
its extremely interesting .
unfortunately its in french , but I will have an friend to read and translate it for me .
just the pictures is worth every cent I payed for it .
its absolutely everything about cannon production , also about powder and fireworks
shows buildings , furnace , machines drawings and everything , including drilling machines for both bore and touch hole , would be possible to build an 18th century gun foundry from this drawings .
it will be very interesting to have it translated .
