Help with identifying these old Workshop Machines

Top beasty is a relatively comprehensive tune-scope, with all the bells and whistles of the day.
The sun machine is an exhaust gas analyser.

Both are cool, and very usefull, however many mechanics these days wouldnt even know how to use the tunescope.

Value. Really hard to say. it all comes down to who whants them on what day.

Analogue scope and 2 gas analyser - good for working on cars with carbs and points, but not much use in the modern world. I have the same 2 gas under a bench, it needs repair.it can't be, and what's the point.
