Correct frog for a No9 Mk1 bayonet?

[Flying10uk]

Were frogs, slings and belts issued in white.........? Please tell me!

Among the various frogs in my militaria collection I only appear to have 3 British examples in white, i.e. white from manufacture and not blancoed white. Only one of those is in webbing material, unissued condition, with the other 2 in nylon, presumably for the L1A1.
