No, it is not so important for this one I think.
Usual ratios are 1.66 (series), 1.85 or 2.35
1.77 is the usual ratio before that you cut the black borders.

I could change the resolution if you'd prefer. Also I what I believe to be a Riley seems to be a Riley 9 Lincock fixed-head coupe.

Thanks for the pictures.
Don't they look a little "high"? I think that the ratio should be 1.85 rather than 1.77 (16:9)
But as the difference isn't big (16 pixels), it is not a major problem

Mucked up the first posting, so here it is again:
