Quartermaster size No. 4 (present day size 42) enlisted pattern infantry frock coat with regulation sky-blue piping at collar and cuffs in excellent condition. Coat body is made of high-quality black wool milton cloth more typical of officer garments. The collar still retains the original size label stitched inside and is printed: SIZE, 2 over LOT. In period ink the numeral 2 is lined through and beneath it is a handwritten "4" (lot number is blank.) The coat retains all its original general service buttons except one on the right cuff and are held in place by its original brown button cording thread. Front body is lined with brown cotton, quilted inside each breast panel, as per federal quartermaster specifications. Off-white linen lines each sleeve and brown glazed cotton was used to construct two deep rear-skirt pockets. Original hook and eye at base of collar.
As demand for blue wool fabric became acute in the early months of the war, federal quartermasters sought temporary fabric substitutes, most notably gray and as seen in this garment, black. Overcoats made of black pilot cloth are well-documented and occasionally surface in collecting circles - here's a less known example of early war Yankee innovation made by an unknown federal contractor. Viewed indoors this coat looks close to dark blue - in sunlight it's true color is manifest.
