This is my chess half-set I designed using my soldiers. Just a quick thing I put together a couple of years ago.
The pawns: My Sikh soldiers
The rooks: Mini towers from my desert Fort style
The knights: Sikh soldiers carrying horse head armour pieces*
The bishops: Officers (because they have pointy hats)
The queen: The CO's wife, on a dais.
The king: The Commanding Officer (a Colonel), on a dais.
*as whole horses wouldn't fit.
THERE IS A FULL SET OF PICS DETAILLING THE PIECES BUT THEY WERE LOST DURING THE BIG BRICKSHELF MATTER LAST YEAR - I have yet to upload them here, if I still have them.
