Fourth. The only element that would allow more precision, would be the stone screw. Its diameter and its pitch (threads per inch or per centimeter). I understand that in ancient weapons there was the "armero step", which does not match the current parameters.
All this I say for the photographs, that despite the good will of the photographer, they always have shortcomings and imperfections. It would be better to have the gun in your hand, like Cerjak .....
