Mr.Moerenhout.
Thank you for reply.
Yes, Chassis number part plate is lost, perhaps to use other car.
Do you mean where is number stamped A to E in photo?
For reference,
My car small alike attached monochrome-photo's car, that is in japanese magazine article.
By Greg paris, this is correction of Michel shoen, famous abarth collector, but Mr shoen didn't remember his car's history.
This car's number is (according to article) 847405, but no evidence this is my car now.
This is all, history link is missing.
