My latest addition to my antique props library. I created/sculpted the model in 3ds Max and ZBrush. Textures are all hand painted and done in Photoshop. For texture baking, I used Substance Painter and 3dCoat.

I didn't find out what the notches on the side of the Irons have been used for. If anybody knows, please let me know...
It is bugging me ;-D
thx
