Hi Paul, please check your references the Doner K3B4B Variant did not carry the additional Chilli sauce armament. 🙂 I believe we may be looking at a Doner K3B4B-WCS

Hummm, I do not think the tomato is the correct shade of red for the period.
It just does not match.

OH!, wait! Maybe its covered in oil, making it look a different coloUr! 😉
