Yes, two black and red keys came in all markets PLUS for 1976 one of the black keys was replaced with the square head lighted key (which most have been thrown out as I think owner's replaced with later keys).
The red/black keys came attached to a red DOM key tag, reproductions of which are available from Orange Bar Products though I don't see it on their website right now, I think they have them. You can find their posting about them here:
