This was the first apparatus used by the Francisco FD when they started up in the 1970's. The last digit is missing from the serial number plate, so a positive historical identification is not yet possible, but they said it came from Pennsylvania. The number we did get, 75S-237?, limits the search to ten possibilities, 2370 to 2379. With the assistance of Brother Martinelli, I have found photos of seven and eliminated each one, narrowing the search to three possibles.
