There is a very interesting report in last issue of Classic Porsche magazine about chassis 1099! Bought new in october 1973 by Carlos Bolanos, from Mexico, than immediately raced at the 1000km of Nürburgring. Was shipped to Mexico later and raced in local events, and eventually 24H Daytona. After different pilots and owners, 1099 was buy in 2004 by his current owner. In 2007, he was lucky to find the original engine in Florida! 1099 is obviously «matching numbers» and possibly the only 2.8 RSR in this case.
