Project Underground NO SERIAL NUMBER

What a cool site! I came across this page while trying to identify this bike I just picked up. The specs and decals sent my spidey senses through the roof. I couldn't leave without it. After actually learning what this thing is, I'm glad I didn't! This thing is insanely clean too.

Am I correct that these should have some sort of serial number?

It should have a serial number stamped on the bottom bracket. But I believe it might not be visible due to the frame being powder coated. The black darts are painted on. I've had 3 of these frames and they all cracked at the head tube. The last one that cracked was like yours and a serial number couldn't be read, but I scraped the powder coating off and the number was visible then. I currently have one that is an NOS teardown that I'm not going to risk riding. It will be for display purposes on my family room wall with a few other bikes. With a nice light air fork they ride really nice.

If you look closely on yours you can make out something on the crank side. Mine is 94094

Thanks Jeff. I'll see if it is clearer once I pull the drivetrain to put in the ultrasonic cleaner.
