From a new book, I got about Norway in the great northern war.
A Norwegian dragoon in cuirass. All illustrations of Norwegian dragoons in this book shows them with the cuirass, including a reenactor.
I've sent a mail to the author, to ask about it. As everybody else says they were left at the depots.
Second interesting thing is is the horse. It's a Fordhest/Fjording an old Norwegian working horse breed. A very good horse. Not very big 135-150cm over the shoulders(most of to days horses are closer to 150 than 135)
Other illustrations do not show the dragoons on this horse. So it wasn't universal for the dragoons. But this is the first hint I've found that the Fjordhest was used as a warhorse.
