The only one I have ever seen in person is this STH-10 in Woodstock, NY. (Hippie land, haha.)
Sorry for all the branches in the way. I took the photo from the parking lot next door because I didn't want to actually pull into the police station and start taking pictures, haha. NY cops can be jerks.
I have seen a Model 2 near a police station somewhere else, but that doesn't count because it's for the firehouse right next to it.
