1st and 2d Captains of guns, and of field and boat howitzers, wear the primer-box in front; if they are boarders, the sword on the left and the pistol-frog on the right hip. These equipments, consequently, will be slid on towards the loop end of the belt, in the order just named.
Other boarders, and guns' crews of howitzers when used as field-guns, wear their arms, as in the preceding case, without the primer-box.
Men armed with muskets, and acting on shore, will wear musket cartridge-boxes, fitted with frog and scabbard for bayonet on the waist-belt.
Men who may be armed with carbines on shore duty will wear cartridge-boxes with waist-belts. For boat duty, or when armed with pistols and swords, they will wear the waist-belt with the proper frog and boxes.
250. Instead of the sword-frog, the sword scabbards of Admiral D.D. Porter's pattern are fitted with a loop to slide on the waist-belt. This scabbard also dispenses with the brass mountings, which are replaced by leather ones. The whole is fastened by copper rivets, instead of being sewed.
251. Primer-Boxes, of black bridle leather, rectangular in form, and of the size to contain, loosely, the tin packing-box. Flap covering the top and front with a button-hole strap one inch in width, sewed near the bottom: brass button riveted to the bottom of the box. Loop, two inches wide, placed upright on the back of the box for the waist-belt to pass through.
252. Pistol-Frog—buff leather—wide enough at the mouth to cover the cock of the pistol, and at the lower part to accommodate the stock; upper part of the back of it turned down to form a loop large enough to admit the waist-belt. The stitches forming the side seams not to come nearer than 0.25 inch from the edges of the leather. To be worn on right hip.
Pocket—thin bridle leather—to contain three cartridges; flap, tongue, and loop.
Cap-pocket, like the cartridge-pocket; lining, a strip of sheepskin with the wool on, glued with fish-glue and sewed to the back at the mouth of the pocket.
These two pockets are of the same depth, and occupy the whole breadth of the pistol-frog.
