It might be the case for some casques, but not likely all.  BP confirmed that one casque was in the Childrens' Zoo at Hermann Park in Houston -- and a quick glance at the list turns up nothing for that location in the NRHP. If it doesn't apply across the board, it's probably not going to be useful for confirming locations, but it could be a good starting place.

also important to note they would just be city confirmers. in that The water tower and the terminal tower are both in the cities but not at all near the casque locations. still all clues are worth looking at
