Legacy Khaki, Shade No. 1, 100% cotton twill field shirt. Ink-stamped: Philadelphia Quartermaster 6421-21 & S-3011C 15 X 31 8405-286-5317 N-0770 QM Depot October 1955 Pattern Date November 1954 Minimal wear, really good shape considering its age, no visible stains, no significant rips, tears, holes or damage to the textile. Some outward bleeding from the inside stamp and 4 tiny ink specks inside the lining (not visible, smaller than ballpoint pen dots). All print is still clearly readable. A few pinholes on collar and the very top-most button is cracked but still fastens, hasnt been replaced since it is original from 1955. Patches are all original to the service garment, seem to have been ironed-on before they were sewn with matching color thread.
