Thanks for the welcome, Fernando. We're almost neighbors
I had always read that the arquebuses were fired without suspension, so my astonishment to see the engravings. I believed that the muskets were first used in the 1560s, and that the very concept of musket supposed use with fork; and arquebuses that were light pieces that did not require fork. But I guess that your explanation that they had heavier pieces that required the use of forks is the logical explanation.
