Silver Body and Burgundy wings with grey leather upholstery was quite a common colour scheme in the 80s and early 90s . Indeed the silver wings with contrasting colour body was used for the Roadster Lightweight competition cars in the 2000s , and this type of combination has remained popular for those who like the two tone Morgans.
If you apply to the factory quoting your chassis number , they should be able to tell you the original colour BUT don't expect an instant answer , things move at a glacial pace in Malvern.
As Tim has said "original" doesn't mean so much with Morgans as it does with other cars . If you are going to respray it then pick a colour/colours that you like , suit both your personality and and the car's , and go with that.
