Why it matters
The RSH is the smallest sub-series of the 1973 Carrera RS 2.7: 17 homologation cars among the 1,525 road-registered RS built. The RS existed to qualify a 2.8-litre racing version for Group 4, which required at least 500 cars, and the RSH cars carry the paperwork and specification details that went to the FIA. Today they are among the rarest and most sought-after 911s.

History
Porsche showed the Carrera RS at the 1972 Paris Auto Show. The first 500 Touring and Sport (Lightweight) cars sold out immediately, and a second and third series of 500 followed at higher prices. Of 1,525 RS built, 200 were M471 Lightweights, 1,308 M472 Tourings and 17 RSH; another 55 were completed as RSR racing cars.
One documented RSH was finished in May 1973 and delivered new through the Dutch importer to the USA. A factory homologation document dated 5 May 1973 records a late-production change of the crankcase from magnesium to aluminium alloy, which explains an engine number prefix that differs from the usual RS. Auction catalogue text also notes that one RSH may have been used to homologate 6-inch and 7-inch Fuchs wheels.
