cool things with wheels, since 2006
The original caption on the link says the big pumper on the right is a Gorham. There is a some info about them on the net. The other two are not identified by make but the smaller one looks like a modified touring car.
Yes, I looked ahead, but ran out of time last night to post more from that source link of photos... and saw that they identify it as a Gorham. I don't recall ever hearing of a Gorham
the Gorham trophy company of New York made the Borg Warner Indy 500 trophy. Hmmm.
Gorham seems to have been tied up with Seagrave. http://www.lafire.com/stations/FS004/FS004_1919-1948.htm I think the history of these big pumpers is a bit complicated as I think many were one-offs or maybe custom built in small batches. I can't find anything on the net about the company but there looks to be plenty about the LA and Long Beach fire departments.
