A heated, but ultimately constructive, argument concerning this article has taken place on its dicussion page. The version to which you reverted it was biased to the point of being a statement from the organisation itself. Please understand that phrases such as

• "Whenever the kilted S.N.G. columns appeared, a shiver of excitement and expectation spread among friends and foes alike."

• "anyone seeing the drum beating, black banner waving , Colour Party in their Black Shirts and kilts couldn’t fail to be impressed and old and young alike flocked to join the ever-swelling ranks"

and

• "it is remarkable that this particular organisation was not destroyed by the British State"

are simply personal points of view rather than verifyable facts and fly in the face of wikipedia's NPOV principle.

Since you seem to be knowledgable on this topic I suggest you devote your efforts to increasing the factural accuracy and quality of this article, rather than simply reverting it back to a previous version.
