The Italians continued to dominate their race after the war, now again on a single big lap through Italy. Mercedes made another good effort in 1952 with the underpowered Mercedes-Benz 300 SL "Gullwing", scoring second with the German crew Karl Kling/Hans Klenk that later in the year would win the Carrera Panamericana. Caracciola, in a comeback attempt, was fourth. Few other non-Italians managed podium finishes in the 1950s, among them Juan Manuel Fangio, Peter Collins and Wolfgang von Trips. In 1955, Mercedes made another attempt at winning the MM, this time with careful preparation and a more powerful car, the Mercedes-Benz 300 SLR which was based on the Formula One car (Mercedes-Benz W196), entirely different from their sports cars carrying the 300 SL name. Both young German Hans Herrmann (who had had remarkable previous efforts with Porsche) and Briton Stirling Moss relied on the support of navigators while Juan Manuel Fangio (car #658) preferred to drive alone as usual, as he considered road races dangerous since his co-pilot was killed in South America. Karl Kling also drove alone, in the fourth Mercedes, #701. Similar to his teammates, Moss and his navigator, motor race journalist Denis Jenkinson, ran a total of six reconnaissance laps beforehand, enabling "Jenks" to make course notes (pace notes) on a scroll of paper 18 ft (540 cm) long that he read from and gave directions to Moss during the race by a coded system of 15 hand signals. Although this undoubtedly helped them, Moss's innate ability was clearly the predominant factor. Moss was competing against drivers with a large amount of local knowledge of the route, so the reconnaissance laps were considered an equaliser, rather than an advantage. Car #704 with Hans Herrmann and Hermann Eger was said to be fastest in the early stages, though. Herrmann had already had a remarkable race in 1954, when the gate on a railroad crossing was lowered in the last moment before the fast train to Rome passed. Driving a very low Porsche 550 Spyder, Herrmann decided it was too late for a brake attempt anyway, knocked on the back of the helmet of his navigator Herbert Linge to make him duck, and they barely passed below the gates and before the train, to the surprise of the spectators. Herrmann was less lucky in 1955, having to abandon the race after a brake failure.
