It is a 1941 International Pirsch aerial belonging to Chatham-Kent Emergency Services. The truck was originally Chatham Fire Department 3and the lettering presently is Chatham F.D. and No. 3-41 indicating that it is unit 3 and built in 1941. The truck was built at the Chatham International Harvester plant and the Pirsch aerial added.
Franklin Township Fire Department
(Columbus, Franklin County, Ohio)
Foam 199, a 1989 International box truck used as a foam wagon.
The box is marked as CMMAA (Columbus Metro Mutual Assistance Association) of which I can find no other record of.
The unit is seen here assisting Washington and Norwich Townships on scene of an overturned fuel tanker at US-33/I-270 in Dublin. A similar crash here in 2017 resulted in a major fire and several days of ramp closures.
Does anyone know where Engine 55 from Firehouse Dog originally served? I was thinking Ottawa but it has a big rear step. If anyone knows or has a picture of it when in service, it would be cool to see.
