Absolutely no wear whatsoever to the piping. It has one small hole right next to the seam under the rear flap of the cap. The interior is choice and is marked size 57 1/2. On the underside of the sweat band it is marked 2./PZ.ABW.44 and is also marked to a maker Brelter Munich and it is also stamped HB 37. I would say this hat has just been in storage as there is no sweat wear whatsover. There is a slight chance there was some mice snipping to the sweatband, though minor.
