OldeWorldCC has made a one of a kind chess set using .50 caliber brass. He is asking $800 for these one off creations. He does make note that when you order one, it will be similar but not exactly like what is seen in the picture due to certain criteria such as parts availability and wood used.

Here are the details of the set:

THE BOARD:

First, note the quarter placed in the images for a size reference. The board for this set was made from jointed pieces of Red Oak.

Individual chambers were made for each .50 caliber bullet shell chess piece. Antique watch gears and hands adorn the sides of the board. Intricate wood burning details are found all over the set. Each set will have its own unique artwork. Holes were bored into the sides and gears were set inside. You can make general requests if you like, and I will do my best to integrate them into my work. While etsy only has space for 5 images, I have shown the best angles I can.

Antique typewriter parts were used for the retaining rails to hold the pieces in. ( Your set may have a different part for the retaining rails, and it may have two rails per side.) The retaining rails are hinged to allow access to pieces. A custom made pin catch/ hasp locks the rail in place. The entire set is clear coated. The board has been dark weathered to give a unique rustic appearance.

Here are the pieces.

THE PIECES:

All shell brass is tumble cleaned and individually inspected before use. Made from used/spent .50 caliber BMG bullet shells, the light side is wire brushed brass, and the dark side is weathered/ black painted brass. Cuts, bends and curls give each piece their proper designation. All pieces are then clear coated.

Measurements are approximate.
Board measurements: 16x16x 2 1/2 inches
Board weight: approx 17 lbs
Pieces height: The height of the pieces range from 1 3/16 to 3 7/8 inches
Pieces width: Base: approx 7/8 inch inch
Total weight: approx 18 lbs
Shipping weight: approx 23 lbs

He offers the chess pieces separately and they cost $245.

He also makes chess pieces out of .223 brass.
