I have Col. Munsons book "The Soldiers Foot and The Military Shoe" 1917 edition. He shows the M1912 as a single sole welt constructions with leather heels and as was typical Army practice a row of square steel nails on the rim of the heel. Smooth out russet. His photo shows an extra vertical row of stitching probably to hold the heel counter, counter cover and upper together to prevent squeaking which goes away on the roughout versions. I personally have never seen a true factory made double sole M17 and I suspect that the heavy welt and heel rand used is sometimes mistaken for a double sole. I have seen some with a half sole applied over what appears to be new soles and then hobnailed. I have also seen (3 pair) of single soles hob nailed and heel plate. I am wondering ( since the army never used hob nails and heel plates before or since)if The QMD authorized their use as a theatre specific item. Mostly I am looking for such an order and specs such as were printed for the m89 shoe. I have the 1916 QMD instuctions to inspectors (vol 2 QMD Manual) and nothing is mentioned about hobs or heel plates and are not listed in any of the tables.
