This is quite a unique piece to handle, especially since I was driving at the time it was handed to me. The texture did feel like it was from a snake or reptile and the initial quick split-second glance at it was enough to make it one very interesting pen. No Parker name was visible anywhere on the pen, but it was definitely a 75 fountain pen.
Please note that I am not certain if this was a prototype made by Parker.
I have found more variations in brown and black.
Here is a red variant.
