Pictured above is an original Prussian infantry tents mess canteen. This canteen is located in the collection of captured Prussian equipment at Esterhazy Privatstiftung, Forchtenstein castle. The photo was obtained from the following work: Hohrath, Daniel. The Uniforms of the Prussian Army under Frederick the Great from 1740 to 1786. Vienna: Verlag Militaria, 2011. Print.
Each six man tent squad (Kameradschaft) was given one Zeltflasche (tent flask) or it was sometimes referred to as a feldflasche (field flask). Each of these "canteens" as they might be called were quite large and heavy when full. They could hold almost two quarts of water when full. They were usually carried by one or two members of the tents mess when marching, and would have been available to the whole squad for use. The flask itself is made of a thin sheet metal, which was most likely tin. The flask has a basic "kidney" shape to it. On each side of the flask are two small "arms" or metal loops that are used to hold the shoulder strap in place. The lid was actually a small inverted cup, which could be used to hand out small amounts of water or any other contents of the flask. The flask was usually affixed with a rudimentary strap, which would have been leather, webbing, or string if necessary.
Pictured above is a reproduction field flask or canteen. The canteen is made of tin, and the lid is affixed to the body of the flask with a piece of string. The strap is a simple piece of webbing just small enough to go through the side arms of the flask. The ends of the webbing are overlapped at the bottom and sewn together to make a continuous loop.
Unfortunately, no original surviving drums belonging to the Regiment von Itzenplitz have been discovered. However, the basic design of the “Prussian” drum used by each regiment was approximately the same. Each drum was made of brass, and featured a shield displayed in the center of the drum. The shield featured the royal cypher “FR” for Fredericks Rex. The FR was centered under a crown surrounded by banners, cannons, and other “honors”. The shield was made from a separate piece of sheet brass, and attached to the barrel of the drum. The drum heads were calf skin. The drum would have featured ¼” linen ropes, and the tugs would have been made from cows leather. The drum featured a screw like snare adjustment on one side. The main difference between regimental drums came with the design painted on the rim of the drum. The rim of the drum was made from wood, and painted in varying designs for each regiment. Each company of the regiment would have had 3 drummers (Tambour) assigned to it.
