Thanks for the advice everyone. The bike ended up going to PS after I had a bit of a chat with one of the people I have previously dealt with there. They have promised to try and do their best to slip it in when they have a free minute. In the end with my lack of transportation I didn't have a huge choice in the matter.
I have also instructed PS to save a sample as per your recommendation. They are going to make sure to get both fuel and the ***** on the top in the sample.
Here is the best sample pic I have. Bad focus from the auto-focus unfortunately. It is indicative though.
