Very impressive Halstuch and Halsbinde. Congratulations. I have yet to find a Halstuch for sale.
Chip, the Halsbinden on AGM each went for $125. One had similarities to the one shown here in terms of ties. It was maker and 1915 date stamped and profusely marked with (Pommern) Bekleidungsamt and unit stamps (I.R. 5, I.B, 2.K., K.B.A.II, size 3). The other Halsbinde was made of a ribbed material and more off-white than Feldgrau in colour. It was unit marked, but I don't recall which. Maybe someone here snagged it.

Just a quick observation: Is Milosz' Halsbinde the earlier cavalry(?) version with smaller bib? The front side looks like it's made of wool, while the 1914 model wasn't, as far as I recall.
