The numbers

This is what I was looking for today.  Engine and Chassis numbers.
Now I have a reference that will allow me to talk with the experts and enthusiasts

Chassis / Frame no.  0301 20181 00

[UPDATE 29may - Ive found more chassis numbers ]

Engine no.  20486

 Im not sure if or how these numbers might assist, but there are very distinct reference numbers cast into the barrel inlet and exhaust manifolds

Inlet manifold no.  9.300.11102.00

Exhaust manifold no.  MR SACM (though Im not absolutely sure about that S)

So just for the record;

Chassis / Frame no.  0301 20181 00  [UPDATE 29may - Ive found more chassis numbers ]
Engine no.   20486
Inlet manifold no.  9.300.11102.00
Exhaust manifold no.  MR SACM
