I designed this play aid at the request of my friend Gordon from Adler Hobby. It holds a 16mm die and has a 'frontage' at the top flat side of 40mm. It's made of two layers of 1/8" (3mm) thick Baltic birch plywood. The marker can be used for Black Powder, Tremble Ye Tirants, British Grenadier or a myriad of other rule sets where the disorder points on a unit is a number from 1 to 6 or less. I'm not sure if Gordon will sell these at his store, use them for personal use or ask me to sell them on my website. Leave a comment here if you're interested in some.
