Try contacting Nan Raphael, she's a leader in military band piccolo literature:

She wrote an excerpt book for band picc literature, and I would bet that she would be able to locate one for you.
Otherwise, take a C piccolo part, and transcribe it. It can be made easy with most music software these days, I'm pretty sure there are free-ware programs that will transcribe. If you're interested, a PM to computer-savvy 8-Notes forum member Jose-Luis should start you on your way.
