Vizefeldwebels were senior NCOs (Unterofficer mit portapee: Militarwochenblatt of 1862). In todays' terms they'd be close to a US E6/7 I reckon. They were the backbone of the army. The Koniggratz cross was a campaign medal; you got it for being there. What is interesting is that your buttonaire lacks the Franco-Prussian war medal, so your ancestor was out of uniform by 1870. The war decoration was a serious award-given for real merit and sometimes, bravery in the field. I would guess it was probably a bravery award for the Austrian war and I think there's a list of total awards out there for the war. If you can find out your ancestor's regiment, maybe we can help you find more information. With the Kaisers' Centennial medal (1897) and the swanky enameled long service schanlle, the buttonaire must date from @ 1900. All veterans who applied received the Centennial medal. The US consul was kept busy at the end of the 19th century handing these out. At the time, the German war veterans associations in the USA were quite large and very,very popular.
