A guide for the quest: Three Wise Monkeys.

Monkey Locations
The first monkey can be found at the cemetary. There should be some Keys around to get through the locked door.
The Second monkey can be found at a bandit camp in a opened red chest SouthWest of Korovie.
The third monkey can be found on a fire place at the H5-5 little lakes.
Once you have the three Monkeys you just need insulating tape to put them all together.
Once you have completed all of these steps you can then travel to Scowling(who also gives the collector quest) at Minaevskaya Mine. He will take the monkeys off your hands for a small penny.
