Model 1910 Sachsen (Saxon) Officer's Schirmmütze for Artillerie, Pioniere and Verkehrstruppen (Verkehrstruppen - Transportation Troops. These included all Eisenbahn (Railway), Telegraphen (Telegraph), Flieger (Flying), Luftschiffer (Balloon and Zeppelin).

This superb Schirmmütze is made from a high quality Feldgrau wool with a black velvet band and officer's Kokarden.

The cap is lined with a cream colored artificial silk with a dark brown leather sweat band.

This example displays one of my favorite characteristics in a field-worn cap, the wear on the bottom interior of the visor from the owners thumb; the result of pulling the cap on hundreds of times in the field.
