Dear all,

I am seeking some help from the experts to solve a riddle about 11810686.

11810686 is supposed to be a 911 L Euro. The engine SN is 6103606 which corresponds to a 2.2 T USA. The engine case is stamped 901/05 which, as far as I know, is an alloy engine case from a 911 2.0 1966.

Any of you knows 11810686 ?
is this possible ?
Your views ?

Cheers
Xavier
