WW2 US Army Enlisted man's service jacket

US Army WWII enlisted man's service jacket worn by a private first class who served in an aviation engineer unit in the Pacific theater of operations. The insignia on this jacket reveals that its owner saw extensive action, participating in four campaigns, and was wounded once. The jacket (pattern of 1939) bears a US Sixth Army patch on the left sleeve and a Far East Air Force patch on the right. The latter patch appears to be an Australian made. The jacket has its original "US" and engineer lapel disks, ribbons (Pacific theater with four battle stars, Philippine liberation with one battle star, WWII Victory, and good conduct), a Presidential unit citation patch on the right cuff, four hash marks on the left sleeve indicating two years of service overseas, and PFC chevrons and a service Stripe. The jacket is a size 36 and shows obvious use, but is nonetheless in very good condition with just minor soiling (shown in photo). It was made by Rose Bros., under a March 1942 contract with the Philadelphia QM Depot.
