Trying to get to the bottom of when the 45 degree roof lead loaded joint line changed. I understand the straight join line was used with the Concrete Moulds with Jaguar Cars not expecting to make that many cars.
The later 90 degree join line shown at the bottom of my photo shows the later join when the new moulds were made. I am told this was from chassis 860480 on.
