how many guns does santiago have ?

From the text:

In the country he wore a .357 Magnum on his belt, and its armoured bullets, according to what he said, could cut a horse in two through the middle. During the partridge season he would also carry his falconry equipment. In the closet he kept a Mannlicher Schoenauer .30-06 rifle, a .300 Holland & Holland Magnum rifle, a .22 Hornet with a double-powered telescopic sight, and a Winchester repeater.

I count five guns.
