Those pricks must have been there for a while, or there was a lot of them! I can't believe they took all that. WTF would they want custom parts that people can track? Luckily for you it seems like they aren't very smart and hopefully that little factoid will lead to them getting caught one way or another. Have you called your local tool guys to see if they can get you enough to get you back in the shop? I feel for you man, a few years ago the space I rented got hit and I was lucky that the neighbor was a retired police officer and heard the thugs. He followed them to where they hid the stuff and then called the law. It still took a week to get my stuff back because of the system. I wish you luck with it and hope justice is served to those thieves!
