Hmm had a quick look following your question above. I only have a very narrow and particular knowledge of the different models as a 'late-comer' to Morgans; and I don't mean to nitpick but there are a few errors in the Aero 8 page regarding years and sequence of 'series' and the relative changes.
BTW it's also good to see you have chosen a particularly nice example of an Aero 8 series 2 (registered as MMC 11 at that time) to show on that page. T'is a very special and powerful car indeed, I know the owner thinks very highly of it

Interesting summaries nonetheless.
