You have all of the ladders produced thus far, but it looks like you are missing the first release of the Pierce Dash which was white over red and marked for El Segundo, CA. There were also two special editions produced in very limited quantities for the MCCH gathering in production runs of 125 and 75, and one for the Toy Fair.

Here are photos of all of the Pierce Dash's from publicsafetydiecast.com
