Morgan do not seem to be very good at noting major modifications in the service documentation. I had to get a letter from them to confirm that my car had a chassis change. That's quite a big thing I would say but they didn't consider it worth noting, unlike an oil change. The only real way to confirm what your car has is a physical check using the lists above, they cover all the big things. You may have to do a bit of research on TM to find out what you are looking for to confirm what has been done.
