XVI century matchlock and barrel, help with more precise dating

[Matchlock]

Now here I proudly present my finely wrought Italian, Tusco-Emilian snap-tinder-/matchlock Landsknecht arquebus of ca. 1525-35.
It is shown at the top on the photo of my four matchlock arquebuses.

For more on it, and on a similar but seven-bareled arquebus !!! in the Army Museum in Prague, please see my threads:
