Hey, I was on some course where I have a lots of free time, so I took Blender in the memory stick to the computer that I used there. Now i can use my timee to something creative. (the computer owned by the company that runs the course and I can't install anything on it)
So I figured out that Blender actually works very well even from the memory stick and I had no anymore boring there...
The model is based on the colt 1894 bisley model, but this is actually my own version about it and it is not so similar. I am not a big fan of the guns, but i think that this kind of old revolvers are little bit more nice than the modern ones.

| New material to the shuck. |

Someone also was really intrested about the metallic material. It is really simple, but if you want to look at it closer, here it is:
