This from Wayne Mutza:

I’m working on a book devoted to “Big Water” apparatus, to include high volume, high pressure rigs, tenders, hose wagons with monitors, etc. Can anyone ID this Cicero engine, especially year, make and GPM? The year 1967 is written on the back. Thank you. I hope you have seen my book covering the history of Milwaukee apparatus, by McFarland Publishing.
