Note the Bramton double sided rear hub
I doubt if that's original equipment.
I think it is, saw many of these just like that in for service long ago, one of the workers had a knack of obtaining these hubs when a double sided hub fitted Gran Prix came in for service and needed a rear wheel...

I laughed, as I was the guy pre building them.
He got to harvest the hub.
