Do you have a Arntz / Butler Cobra?

Hello
I'm trying to put some history together on a
US made Cobra that were sold world wide the company was The Arntz Cobra out of San Francisco,California,USA from 1974 to the
early 80s. (Arntz was probably one of the
first Cobra replicas made and it was an
Arntz that spawned the UK Cobra replicas.

I'm looking for anybody that has a Arntz
Cobra or had one or built one or anyone that
has any info from that company. I would also
like to talk to anybody with a Butler Cobra
(Ron Butler Ex Ken Miles mechanic)

Please pass this message on to anybody that
knows of one

Thank You
Steven Frazier
