67 Speed Warning Dash

[Shaun1162]

Picked this up the other day, and I know a little about them, but no idea what it's really worth. The strip on the back is dated 66 (hard to see in photos). Seems like the speed warning set up has to be cleaned because the knob doesn't move like it should, but the needle will still go up and down.

Needs a new knob for the adjustment, and it didn't come with the wiring or the buzzer... Kind of on the fence as to sell it, or put the speed warning in my tach dash.

Any help is appreciated, thanks
