The reference picture below was found on a World War 2 site that
sells memorabilia. I decided not to 'cheat' this time and painted
the texture from scratch using Photoshop and my Wacom ArtPad.
The model will be made into a 'working' flare gun by White Rabbit
[yes, creator of the famous Multiplayer Model Pack!] that will
light an area when fired.
I've included
the next couple of shots in order to show a tiny sample of what
it takes to create a model.

The Japanese
flare gun picture used to create the model and texture.
This is the texture map
under development.

Here is a shot of the model
inside the game.
