[quote name='Rpaterson33' post='251293' date='Oct 2 2008, 13:39 ']Sunsets a 1956, putnam a 1960... common sense (if its all true) would say sunset was the first. Id have to look and see when mack started producing diesels but the B 61 tractors had them way before they were put into fire trucks. I know of B 61s around 1956 and so that have diesels in them, so its all possible.[/quote]
Mack advertising at the time promoted three B model pumpers sold to Hamilton Bermuda as the first diesel powered Mack fire trucks.
