The M3 was the standard U. S. Army binocular of WWII. It was made by Nash-Kelvinator and Westinghouse. The marking H.M.R. is maybe the initials of an inspection team responsible for the ordnance material accepted by the Army, could mean "High Moisture Resistance". The production was stopped in 1944 with this being an early model. The binoculars also have a sight gauge reticle in left tube. This example is marked clearly on the left plate with BINOCULAR / M3 / 6 X 30 , and the right plate is marked with manufacturer and date: WESTINGHOUSE / 1943 H.M.R. On the end of the hinge they are marked with serial number NO. 118872.

112th Infantry:

The regiment was again called to active federal service on 17 February 1941, 10 months prior to the attack on Pearl Harbor. After years of training, the unit first entered the continent of Europe on the Normandy beaches following the D-Day landing. It became the 112th Infantry Regimental Combat Team which consisted of the 112th Infantry Regiment, the 229th Field Artillery Battalion, the 103rd Engineer Battalion, Company C, 447th Antiaircraft Artillery Battalion, and Company C, 630th Tank Destroyer Battalion. 28th Division commander James E. Wharton was in his first day of command when a German sniper shot him while he was at the 112th Infantry's command post.

The regiment plowed through France and Germany, participating in the capture of Paris and the bitter fighting in the Huertgen Forest. At one point, after the fight for Kommerscheidt, the regiment was reduced to 300 men.

During December 1944, the 112th Infantry Regimental Combat Team was holding a 6-1/2 mile long sector which the Germans attacked with nine divisions. The unit inflicted 1600 casualties and destroyed eighteen tanks during nine days of continuous action, that was later known as the Battle of the Bulge. The regiment was awarded battle streamers marked Normandy, Northern France, Ardennes-Alsace, Rhineland, and Central Europe for its service in World War II. The unit was also awarded the Distinguished Unit Citation for its actions during the Battle of the Bulge, from 16 to 24 December 1944. The unit was mustered out of federal service on 6 December 1945 at Camp Gordon, Georgia. The 112th remained an organic unit of the 28th Infantry Division throughout World War II.
