I have been looking around at the different flag companies and sources and thought I would put them all here in one place. You could buy the Osprey books, scan, modify and print them. But why when you have so many good options on line. Hope you find it useful and if you have any comments on who to use please feel free to comment.

A Dorset, UK company. They have 15mm flags and quite a lot. The menu system is not the easiest to track down what they have under Napoleonics. They all seem to sell in sets of six flags at £2 each.
