The brass handles on this chest are fixed with posts that pass right through the drawer front, and there is a reason for going to that trouble.
A swan-neck handle is a bail - a swinging loop. Every time a drawer is closed the bail drops and lands, and it does that thousands of times over the life of the piece. Two things follow from it.
The first is where the bail lands. If it falls straight onto the polished drawer front, it will eventually wear a bright mark into the finish on both sides of the handle. So the back plate is shaped and positioned so the bail comes to rest on brass, not on timber.
The second is how the handle is held. Screws driven into the front from outside would work loose under that repeated small shock, and each time they were tightened they would bite less. Instead the posts pass through the drawer front and are secured with a nut on the inside, so the fixing is mechanical and can simply be tightened by hand from within the drawer if it ever needs it.
Neither is visible when you look at the chest. Both are visible in fifteen years.
