[PIC] Is this the original turn signal lever?

I have a '68 Fastback GT with Deluxe Interior, below you will find a picture of the turn signal lever in question.

I was told this is not the original lever. Does anyone know whether it is or not? If it isn't, what is it from? It was pretty rusty but once I polished it up it looked great. However, if it isn't original I will probably buy a reproduction.

Not totally sure, but I don't think so. It looks like late 70's to mid 80's GM. Ford levers had smaller knobs on the end. The Parts catalog I just looked at show all chrome or one with a black knob, but they are the same size.
