Can anybody tell me what this is and what it is called? It is mounted to the dash of my 1956 f6

 

The large clock and speedo together is called a tach-o-graph, the valve is for trailer brakes and the red button is the control for the 2 speed rear axle.

 

Can the tach-o-graph have a paper feed out?
The valve works my brakes on the back axle
Thanks for the help!

 

Has been a while since I last looked at one, but I think they had some sort of paper disc that printed the speed and time over the trip.

 

Back brake control? I definitely see some stunt driving or "drifting" possibilities!

 

We had tachometer cards on our tractors (truck) in the late 60's that resembled that. The corporation wanted to see the speed and rpm after every run. I quess they wanted to know what was so hard on the running gear.

Rpm and speed was recorded on a circle graph.

 

Me likes the way you see it! My thoughts exactly!

 

We also used them in the fleet I worked on . The boys did'nt like them much.

 

So it is like a old school black box?

 

Most of them had a piece of plastic over the speedometerso if you didn't want the speedometer to show over say 60 mph you could take a straight pin and a Bic lighter, heat the pin and stick it right through the plastic, never over 60 but don't forget to take the pin out at the end of your trip.

 

Can I pull it out and use the stock speedometer ? Can I put a air lever of some kind on the shifter for the back brakes?
