IR 49
Heinrich von Hess 19th century Austrian general was the owner of the 49th infantry regiment. I wrote about him and the beautiful fire enamel regimental insignia decorated with his coat of arms once here. The current entry is also related to the regiment’s Kappenabzeichen and regiment owner. Both can be seen on a thin plaque the size of a cap badge. I believe it may have been a jubilee badge.
I also uploaded a letter seal with the general’s portrait, which can be seen below.
