BSA B22 Empire Star

[Gavey]

Hi, I have just acquired a 1938 Empire Star 250cc. Mostly original, just needs a bit of tidying up.. The paint on the tank has bubbled where the chrome was and I was hoping someone could give me the correct paint colour for the tank, - I may as well do it right as It needs doing. The catalogue and parts book both list the colour as Empire Star green, whereas the non  empire star B models are listed as BSA green.
