In my isolation on the most remote island in the Pacific Ocean, I found myself painting miniatures again. I am working on some French Dragoons circa 1810. I pulled out my trusty Osprey Men-at-Arms "Napoleon's Dragoons and Lancers" by Emir Bukhari, published in 1976. It is so old it does not even have a Men-at-Arms number and the cover is yellow with age. . . it was probably one of the first 30 Napoleonic books I bought. But I digress. . . So I flip the book over to see how much it cost. . . £1.75. . . which considering what wages were back then, it was not inexpensive. (As a second lieutenant I was making about $1200 a month before taxes.)
I checked the Osprey website and a current Men-at-Arms is £12.
Are you familiar with On Military Matters? I have found it an excellent source of material over the years.
