DOES AND CAN NOT WORK!
As you can see in picture 1, the item ID 1834 is the ID for the VSS Katana, which is a Cap gun and cannot be added with the gun adder.
The other items are just random Codes with no specified items as you can see in picture 2 and 3.
The real code for the M92FS Engrave (and not Golden Barret) is 324 and it also DOESN'T work as you can see in picture 4.
I hope this answers all questions.
