Unknown Field Communications Unit

City of Westerville, Franklin County, Ohio
Field Communications 111
Operated as part of the Northwest Area Strike Team (NAS-T), a multi agency hazmat team comprised of several Columbus suburbs.
I have not been able to find any manufacturer or year information on this unit. It looks similar to a unit with roll up compartments that once ran as a heavy rescue in neighboring Washington Township (Dublin), but I have found even less info on that unit.
