Just to conclude this, in my research so far, the highest chassis number I found with the 130 prefix is #0128.
Meanwhile, I've been able to contact a few people with excellent knowledge and expertise in regard to the Abarth GTs of the late fifties/early sixties and I'll post a write-up on the Abarth-Simca 1300 shortly.
My first real experience of Abarth cars was at Radbournes shortly before they lost the import concession, but, though that was long ago now, the Corso Marche coupes of that era still seem to me amongst the very nicest cars ever to turn a wheel!
