About Quiz #358 : 1924/5 Gräf und Stift SR4


graef _stift_6_cylinder_1920_470
Ooops that was a bit painfull, that we inadvertedly published the name of the car within the quiz. Sorry for that! Several visitors told us about the mishap. After which we added a note that it was still possible to come up with the exact type and more. Just a few competitors took the trouble to do so: best answer without a shade of doubt - however not fully correct - was by Howard Morgan: "1925 Gräf & Stift S3 model with 6 cylinder OHV engine of 7.7 litres developing 110bhp."  

Sender of the photos is Karl Marschhofer who is collecting Austrian made automobiles. The car depicted is a SR4, the difference with the earlier SR3 is that the V-shaped radiator gave place to a flat radiator with the change of model at the end of 1924. With the same model change also the valve arrangement changed. Depicted here the the S3 engine with one cylinderblock for all 6 cylinders, we understand the SR4 had an OHV arrangement but correct us if we are wrong. Detailed Gräf & Stift information is hard to get. Anyway, Howard's answer was the best we received so he is this weeks winner. Congratulations!

Gräf & Stift made no more than 5000 vehicles in total of which number is known that 119 have survived. Possibly a few more which are not known yet. So please let us know if you heard of a Gräf & Stift hiding in Argentina, New Zealand or Tibet.

Can any one confirm if the Gräf & Stift S3 model ran on 12 or 6 Volts bateries? Did these cars have a double batery set similar to the Isotta-Fraschini ?

We can also remember that 100 years ago, the immediate trigger for WWI was the 28 June 1914 assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo in a Graef & Stift, actually available in a museum but I don't remember where...
