Today's update on the coil issue.
I forgot to mention in the first post that this car also has an electronic ignition in place of the points. It was on the car when I purchased it and it has ran well so I left it there.
I am still using the Bosch 12v blue coil with a resistance of 3.3, but today I removed the external inline resister. After a long drive the coil temperature was much lower than before and everything else seems to be as it should. The coil is still slightly warmer than my other model A with modern style points, but I think the temperature now is very acceptable. I am going to monitor it for a while and if things continue to be as they should I think I will call that good.
Thanks to all who replied. A lot of good information.
