1903-1908 experimental cups
Here are some cups from my collection and some of what I have learned (please correct me if not accurate). The two granite-ware cups are commonly described as "1903 Experimental Cup". The army was looking for a more compact design than the current tall 1874 pattern tin cup that could fit in the haversack rather than dangle from it. The then popular granite-ware proved to be unsuitable for the army. I suspect the tin plated version came along a couple of years later after they found the granite-ware to be poisonous with acidic foods like tomatoes. The aluminum cup dated 1908 was probably the last trial or experimental cup before the adoption of the M1910 canteen and cup.
Cups M1908 aluminum, and WWI purchase
By the 1890s aluminum had become a material of interest for field mess equipment by European armies and the Prussian and French armies issued aluminum equipment. There was interest in the material by the U.S. Army, and the occasional experimental and field trials of aluminum equipment from 1894 to 1905 the material was reported unsuitable for general issue.
The first aluminum cups sent for trial were identical in construction to the seamless tin cup that had been adopted in 1900 and was currently manufactured at Rock Island Arsenal. At the request of the Chief Ordnance Officer at the Manila Ordnance Depot in 1901 1000 aluminum cups were prepared by Rock Island Arsenal and sent to the Philippines for field trial. A serviceable aluminum cup similar to the seamless tin cup, was adopted in 1906 for general issue, and was also acquired by the U.S. Navy.
Rock Island Arsenal in 1907 manufactured 300 aluminum canteens for field trial. The cavalry officers that reported on the aluminum canteens also commented on the unserviceability of the web canteen strap, and that the cup could not be carried in the manner specified in regulations (with the strap threaded through the handle of the cup). As a consequence changes were made to the equipment intended for mounted use.
One of the changes was the cup was made shallower so that it could be carried in the saddle bags. The aluminum material cup adopted was the Model of 1908 that was listed in Ordnance Memoranda No. 1719 as "Cup, Model of 1908, Experimental." (As a consequence collectors that have seen O.M.No.1719 believe the cup experimental.) This cup was manufactured by Rock Island Arsenal in large quantities from 1908 to 1910. The Cup, M1908 was apparently not a popular item with cavalry soldiers and they were often photographed in use by militia troops. The story of the cavalry issue of the canteen cup M1910 begins with the Cavalry Board Report of 1912. By 1914 cavalry troops equipped with McClellan horse equipment were authorized the canteen M1910, canteen cup M1910, and canteen cover (dismounted) M1910. This cup was also acquired by the U.S. Navy.
As to the tin and porcelain plated cups that were similar in general dimensions to the aluminum cup M1908, there is a photographic illustration in a Quartermaster manual that appears to be similar cup that was part of a leather working tool set that was apparently intended for use to hold water as there is a sponge next to the cup.
The documentary and photographic evidence clearly demonstrate that these cups were purchased by the Ordnance department along with tin plated meat cans, plates, and utensils starting in the summer of 1917 for use by the recruits in camp, until sufficient supplies of M1910 equipment could be manufactured. The manufacture of meat can M1910 was short of requirements and additional similar "off the shelf" mess equipment was acquire by purchase orders in 1918. This equipment was classified obsolete in 1919 and sold through public auction.
Comment: There is general belief by militaria collectors that the tin and porcelain cups were acquired and issued during the emergency of 1898. There is documentation of Quartermaster officers authorized to local purchase mess equipment from dry goods and hardware stores, however, this was strictly "off the shelf" equipment intended for camp and garrison use until the manufacture of standard items caught up with demand.
