Hi I have had a look under my bonnet and in the hidden compartments in the boot for a paint code sticker and cannot find one
Is it placed anywhere else? If. Could find it that would be the most useful

Using the search function on this site it appears that Scott's green is listed as
388 and 388A

Is this correct? Does this mean there are two different shades or could there be more?
Is there any way to find out for certain if it is either colour?

I have never noticed different shades of Scott's green and I'm assuming the "a" would make it a totally different colour

Any help or pointers would be greatly appreciated

Have the paint shop mix up a sample of both in a small touch up size bottle. Won't cost much.

My paint was defo 388A and doesn't match the rest of the car.

Or take the wing mirror to the paint place. Take minutes to get one off.
