61 ish windshield washers are these rare?

[sigshooter]

I was in the local scrap yard when I ran across about a 61 1 ton custom cab big window wrecker. I only do 456 years but I had to look it over.
It had all the chrome knobs still and I noticed it had a washer button sticking thru the knob. I got all the knobs and the wiper switch, including the choke cable and throttle cable.
I left the wiper motor, and chrome floor vent knobs and cables.

Is any of this rare for these models? Should I go get the other stuff? I don't need it but I thought someone on here might
