As I said, I own a GKR palash, not as beautiful as the one on regimentals , as said upon returning from holiday I made some photographs, (as you asked for)
the Sword Knot has red threads, so I Think it württemberg, but as it was attached to the sword when I bought it il leave it "as is" ,
(I bought it years ago because I have a GKR EM helmet; officer kuras front plate, feldgrau GKR mutze, white blue mutze and tellermutze, and EM GKR sabretache, thought it looked nice together, but when I made the bigger cupboard display with some uniforms, (it is next to my Uhlan, and artillery uniform) I put the palash next to the line-regiment officer Kurass on display, see photo)
It was so long I had to cut a smal piece in the shelf to fit it in the display next to an officers Kuras (an enlisted mans old pattern kurassier helmet (Franco prussian war) on top as I don't own (or can afford) an Kurassier officer one ...)
as I am mainly a headgear collector (all countries WW1), I don't really know a lot about edged weapons, but I like it a lot with the engravings.
Furhtermore I wonder is this an enlisted man's sword? or could it be an officer?,should I detach the sword knot?
