Crazy Wolfgang

Crazy Wolfgang is an eccentric Caravan Merchant specializing in the sale of junk. His inventory includes random bits and pieces used for constructing weapons, and also a copy of Rock-It Launcher schematics. Crazy Wolfgang's local inventory can be found in Uncle Roe's house in the first metal box in the corner. Crazy Wolfgang's Supply Key can be recovered from his corpse.

Unmarked Quest: Merchant Empire
Initially, his repair skill is at 15%, but after talking to Uncle Roe for further Caravan Merchant investment, his inventory will expand, and his repair skill jumps to a maximum of 75, the highest in the game (allowing him to repair items to a max of 85%). If you reverse pickpocket a near fully repaired +5 Repair article of clothing he can repair up to 88%. Note that after the second investment he also sells Pre-War Books, however these books have purple covers and cannot be traded in at Arlington Library. After the second investment, he rewards you with 5-7 Stealth Boys, depending on your level.

Location
Crazy Wolfgang, like all merchants, follows a winding course around the eastern half of the map, stopping at Megaton, Rivet City, and several other locations.

Trivia
Agatha includes a shout out to her "old friend" Crazy Wolfgang in her broadcast, saying "No one can scour the Wasteland and find such oddities as you".

Bugs

 * Usually, if you successfully pickpocket Wolfgang and steal his Rock-It Launcher schematics, extremely hard considering the value, you can then immediately buy another from him, giving you two schematics for the price of one.(unconfirmed)


 * Once, when talking to Wolfgang amount the investment, he had a glitch where he waved his arms around (similar to the way conductors wave their arms) and his head spun all the way around (making his head upside down/in his chest for a few seconds). This stops when you end the conversation.
