Change Weapon via Script?

[Devistute]

So i have tried to find a way to change Player's current weapon to another via script, using playMaker's "Send Message" and variety of other ways.
Unfortunately i have not found an way in the last weeks, and decided to give up and come ask here for help 
The idea here is to have two versions of the said "Weapon", and switch them around when needed as they are different. *Its about Torch.

Help would be epic

Take a look into the Inventory demo scene, there is several examples about how to manipulate items there ;)
