Near the end of WW1, the US Government purchased approximately 1800 Winchester model 1894 saddle ring carbine, all in .30-30 caliber. They were all stamped US with the ordnance bomb on the top of the receiver ring. Today, collectors call these carbines "Spruce Guns". To make a long story short, these carbines were issued to troups who were assigned to guard the Spruce forests and lumber mills of the Pacific Northwest. Why, you ask? Because Spruce was the primary wood used in building airplanes for combat over France. I've owned two of these guns over the past 40 years. I bought one in Sandpoint, Idaho in the late 60's and another one in Spokane, Washington about four years ago. Anyone interested should be able to check the internet for an article about these Winchesters, written by Rick Hill (a member of the Winchester Arms Collectors Association).
