Speaking of objective descriptions, you're going to need to give a very complete description of your gun in order for us to even have a tinker's chance at telling you anything about it.
Better yet, good, CLEAR photographs. And by clear photographs, that includes photos of the markings on your gun.
The best way to do that is to figure out if your camera has a Macro setting. If it does, that will allow you to take clear close ups.
