Tell me more about your knob

[402Bowtie]

Over the years there have been many peculiarities pointed out on these trucks. Here's another one I'm wondering about:

For trucks equipped with the NL2 option (which I believe was only offered in '72 for that RPO), regarding the knob on the dash,

1) Was a NL2 deluxe knob offered?
2) If yes, then what trucks received a deluxe NL2 knob?

I thought that only Cheyennes and Supers would receive a deluxe knob. Others have told me that all trucks received this knob in the "standard" version.

I have recently found a few pictures that have confused me even more. Wondering if it could be another difference depending on the factory? What are your thoughts?

The first pic has a deluxe knob but standard foot pedals...???
The last pic is advertised as a mostly original Cheyenne and it has a standard knob.
