That must be a nickname. We can only work with actual names if we are to communicate on this topic.

that is is name he played for Castleford in the 1986 Challenge cup final

I'd stick in Manly's Paul Shaw , Salford's Stand off for the 88-89 season.

Not a Rugby Player , more a Magician.
he featured in the 87 Wigan / Manly game, then terrorized Wigan again in the 88 Lancashire Cup final where he was given Man of the Match award despite finishing on the losing side .

unfortunately , Salford didn't have the pack to protect their Stand off , and he was the recipient of some ' unfair treatment' most notably by Paul ' Buffer' Forber at a saints away game that left him Hospitalised .
Years Later when Forber joined Salford he was asked about the Paul Shaw incident and said that the coach told him to "rough him up a bit."
But justice prevailed. The day he signed for us an old lady went up to him , hit him over the head with her umbrella, and said "That's for Paul Shaw".

Why, Gordon Tallis has counted as aboriginal indigineos but openly admits he has no real proof just been told one of his great grandparents my be or is part aboriginal, I have a great grandparent who is Irish but would never claim to be irish. Mc Kenna never struck me as looking particularly aboriginal and never heard it be mentioned before.

Tallis was clearly Aboriginal. One look at him and anyone who was brought up around Aboriginal families would pick out his features. Skin colour isn't always a good indicator with Aboriginality. I once had a girlfriend who was so blond and fair that she could pass for Swedish, but both her parents and her brother and sister were all very dark skinned and had Aboriginal features. In fact, in the district I live in, half the people I know to have Aboriginal heritage couldn't be identified by a casual observer. One family is all red headed and freckled.
