This is a Dutch Army Military Cap / Kepie model 1916 M16 (laag model) with gold embroidered coackarde, indicating it was for a “adjudant onderofficier/subalterne officier or hoofdofficier”.
For Infanterie Regiment 16 as indicated by the number on the front.
Made by E. Esders from Rotterdam.
In pretty good condition for it’s age. The outside very good, the purple inside has some wear and tear and the liner is partially loose on one edge, this is all not visible from the outside. A few age spots on the edge, but actually pretty good for it’s age.
These early low model caps are hard to find!
