Chip, it was a confusing tunic to me also, but when Tony S. of The Kaiser's Bunker looked at it he said it was OK. Here are my notes from Tony. You will see that the cuffs on a IR40 Dunkelblau Waffenrock should just be red, no piping and the epaulettes would be blue. OK, in 1915 the Friedensuniform Feldgrau regulations changed the board/strap underlay to white and added the old board/strap color of blue to the piping on the cuffs. But, that applied to Feldgrau Friedensuniform. My friends and I discussed this tunic, and it appears to be just that, a tunic made post-1915 with the colors for the M1915 Friedensuniform regulations which is highly unusual to say the least. For a private purchase tunic, there is no difference between a officers or Mannschaften tunic, just straps vs. epaulettes. But of course, officers have that braid loop, while men have the straps sewn in. Blue piping on the cuff could be any number of regts, but here is no other explanation for the white based epaulettes. Does that make sense?
