Hi Eien.
I don't know where you might find a Warlock II, but your best bet will be checking online auctions and dealer inventories. I have a decent list of dealers posted on VintAxe. Start clicking
You also have the option of purchasing a new Warlock that has styling and build characteristics very similar to the old Warlock II. The current Warlock Exotic has the same headstock profile as the Warlock II and is also a mahogany body neck thru guitar. Here is an example of one up on eBay:
The Warlock NJ Deluxe is also pretty similar to the Warlock II but it's reverse headstock isn't quite the same shape as the II.
