If it survived 1940 and still existed in 1941, it could go here--but it should be in the markings it carried in 1941.
The RAF did make some changes to its markings between late '40 and '41. The port wing was again painted black or "night," until the Spring. In August '41, RAF also dropped Dark Earth in favor of Dark Green/Ocean Grey/Medium Sea Grey, with a rear fuselage band of Sky or some kind of light blue or grey.
If you can see the tiny captions, here's an overview I found on pinterest, where I got the information.
Alternatively, you can still enter it in the "1939-40 GB," and enter something else for the '41 GB. There's a lot of time left till 2020, and it would be great to have you build something for it!
