Do you mean left as in viewed from the aircraft so towards the viewer or to the rear of the aircraft? I have just been focussing on the smaller fins this afternoon so I haven't really looked at the other differences.
Here is. Please notice also how the re-engined "S" has the exhaust coming out pretty much more than old "G". Later S-ASA models has also a warning receiver under the fuselage (but that is another matter)
that receiver is only in the S-ASA (old) not the S-ASA-M (AFAIK). So firstly check what version you're going to reproduce before applying it. In the meanwhile I am looking for better pictures, though it's quite hard
Better! I know, being all white is very hard to highlight properly. May I suggest a bit more of light in the reflection just close to the exhaust? I made a trial..
