Hello for all,
I have just discovered that there were also 15000 series, this is the first French Sandcast discovered in the 15000 series, this is the engine number E-1015525.
We knew that there were 14000 and 17000 series but to discover that there were also 15000 series is really exceptional!
this engine was used in competition, and this explains why the crankshaft was cut and you will also notice that it has its famous 9/10 clutch cover with the tenth hole not drilled like the 14000 and 17000 series, and let's not forget that E-1007414 also had this same cover 9/10 !
