This vintage coat was made in the 1890s-early 1900s from buffalo fur for the North West Mounted Police. The North West Mounted Police was founded in 1873 and existed until 1904, when it was succeeded by the Royal North West Mounted Police, then by the Royal Canadian Mounted Police in 1920. This bears the NWMP buttons of the earliest iteration. The coat has a broad shawl collar and double breasted closure, with distinctive leather straps on the front. It has leather reinforcement to the lining at the underarms and by the collar, as well as riveted leather reinforcement at the vent.

The big difference between a boss of the plains and a campaign hat is the grommets. An army campaign hat has them. A boss of the plains does not. Typically a boss of the plains stays uncreased, while a campaign hat gets a four point montana peak. This is a boss of the plains that has been adapted for NPS service.
