1971 BMW E9 3.0 CSL (06)

Introduced in May 1972, the 3.0CSL was a homologation special built to make the car eligible for racing in the European Touring Car Championship. The "L" in the designation meant "leicht" (light), unlike in other BMW designations, where it meant "lang" (long). The lightness was achieved by using thinner steel to build the unit body, deleting the trim and soundproofing, using aluminium alloy doors, bonnets, and boot lids, and using Perspex side windows. The five hundred 3.0CSLs exported to the United Kingdom were not quite as light as the others, as the importer had insisted on retaining the soundproofing, electric windows, and stock E9 bumpers on these cars.
Initially using the same engine as the 3.0CS, the 3.0CSL was given a very small increase in displacement to 3,003 cc (183.3 cu in) by increasing the engine bore by one quarter of a millimetre. This was done in August 1972 to allow the CSL to be raced in the "over three litre" racing category, allowing for some increase in displacement in the racing cars. In 1973, the engine in the 3.0CSL was given another, more subtantial increase in displacement to 3,153 cc (192.4 cu in) by increasing the stroke to 84 mm (3.3 in). This final version of the 3.0CSL was homologated in July 1973 along with an aerodynamic package including a large air dam, short fins running along the front fenders, a spoiler above and behind the trailing edge of the roof, and a tall rear wing. The rear wings were not installed at the factory, but were left in the boot for installation after purchase. This was done because the wings were illegal for use on German roads. The full aero package earned the racing CSLs the nickname "Batmobile".

Ab 1971 entstanden die ersten 3.0-CSL-Coupés in Zusammenarbeit mit Alpina als Homologationserie für den Tourenwagensport, in dem BMW damals mit den BMW 02 sehr erfolgreich war. Der Name CSL (Coupe Sport Leichtbau) war Programm, da die Leichtbau-Coupés gegenüber dem 3.0 CS keine Leistungssteigerung erhielten, sondern dank konsequenter Gewichtssparmaßnahmen leer nur noch 1165 kg wogen und in lediglich 7,4 Sekunden auf 100 km/h beschleunigten. Von diesen Fahrzeugen wurden nur 169 Exemplare gebaut.
Ab August 1972 wurde die D-Jetronic-Einspritzung auch im 3.0 CSL eingesetzt. Trotz gegenüber dem 3.0 CSi leicht erhöhtem Hubraum (3003 statt 2985 cm³) leisten diese Fahrzeuge ebenfalls 200 PS und erreichen 220 km/h, beschleunigen jedoch in nur 6,9 Sekunden von 0 auf 100 km/h. Von diesem zweiten Produktionslauf des BMW 3.0 CSL entstanden bis August 1973 insgesamt 939 Exemplare, davon 500 mit Rechtslenkung.
Die dritte und letzte Ausbaustufe des 3.0 CSL (Juli 1973 bis November 1975) schöpfte 206 PS aus 3153 cm³. Ihren Spitznamen „Batmobil“ verdankt sie einem umfangreichen Aerodynamikpaket, insbesondere dem riesigen Heckflügel, der mangels Straßenzulassung im Kofferraum des Fahrzeugs verstaut ausgeliefert wurde. Der damalige BMW-Rennfahrer Hans-Joachim Stuck wurde an einer Tankstelle, als er mit seinem „Dienst-CSL“ unterwegs war, gefragt, ob dieser Heckflügel „ein neuer Ski-Halter sei“.
Der BMW 3.0 CSL gilt als erstes Produkt der späteren BMW Motorsport GmbH, damals noch eine Abteilung von BMW, und kann somit als der allererste „M“-BMW bezeichnet werden. Der Wagen trug auch bereits die Farben der späteren M-GmbH.

Bottom of clay pot, Kabala, Sierra Leone (West Africa)

Photo taken in 1967 or 1968. This was probably originally used as a cooking pot, but was being used as a water-storage pot in the 1960s.
Very rough notes on pottery making collected by Edward Conteh and me in Kamabai, Sierra Leone from a Limba potter (the techniques might have been different for the pictured pot):
Pots made from white ant's hill clay (fá`a). Millet stalks mixed with clay; clay pounded together with the stalks. She then makes a coil out of the clay by turning it between her hands. Makes the mouth of the pot first in a coil and then builds the coils up and around, piling them on top of one another. Uses a calabash to shape the bottom and then sets the pot out in the sun to dry. The coils come up about four-fifths of the way to the bottom. Initial drying takes about 4 or 5 days during the dry season and 6 or seven days or more, depending on the weather, during the rainy season. Kukuthea [I haven't found what this is called in English yet] is pounded and put in a calabash and mixed with water. The pot is fired upside-down with a pile of dry material under and around it. Upside-down so that the pot's inside will get very hot. She uses a stick to pull the pot from the fire by putting it underneath and lifting it out. The pot is then put into the calabash full of water and kukuthea which will then boil if the pot is good. Kukuthea's action is somewhat like a cementing. The pot is left in the kukuthea mixture for just a few minutes and then taken out to become very dry and strong. If she knocks on it and it sounds like a calabash, then it is a good pot. If not, it sounds like dry mud. It's left on the fire until it gets very red (?1 1/2 hours?). They decorated the pots in the past; one person would use only one decoration, and they would be decorated for buyer appeal. One with fine decorations one would say was a fine pot. Not all people used to decorate the country pots. Decorations put on before putting them in the sun. This woman used her finger only to decorate, but says others used to decorate their pots with sticks. Very small pots were used to cook medicines [this appears to have been the case in other parts of Norther Sierra Leone also]. Other small pots were used for putting pepper in while eating (sort of a serving plate) and others were used for cooking sauces, etc. The very big ones were used for storing water. The biggest country pot she has ever seen was about 2 1/2 feet across and 2 feet high. Very small pots still used for medicine in the 1960s.
