Technical Auction find...ID these tail lights ?

Found a few things at the auction. Anyone know what these tail lights came off of? Thanks.

 

Nice finds. The taillights look like 37 to maybe 40 Buick. We had a 37 Buick 4dr convertible that had similar lights.

 

Yep, they're 39 to 40 Buick according to a search and ebay listings

 

Hold it on the end of a spinning shaft to check shaft RPM.

 

hand tachometer;
Is useful for setting cylinder speed on machines like presses or farm combines.
There was usually a divot or c'drill hole on the end of the shaft that the rubber tip would be pressed into.
We had something similar that my Dad used on an AC 60 combine to set the cylinder speed for specific crops

(saltflats beat me to it)

 

The tach tool is shown below out of the box in bottom photo. Rubber drive end at bottom was held against fan belt with engine running for idle speed.

 

Thanks for the replies. I thought AC Delco too when I saw it. Didn't know what a hand tach was....

 

Good Stuff!

 

Nope. Think about it. If that rubber drive end was held against the fan belt it would read WAY more RPM than if it was used correctly, which is by pressing the rubber tip to the center of the rotating shaft.

Don't bother picturing it, that's not the way it is used.

 

that's the AC Delco logo....

tractor company looks like this

 

I used a contact tachometer at work in the power plant for all kinds of rotating equipment. That is until the strobe tach was invented. The real advantage to a strobe tach is that it isn't necessary to get your hands near moving machinery.

 

Big farm machine for harvesting grain crops.

 

Didn't mean to imply that was an Allis-Chalmers tool.
A quick search turns up a lot of AC Hand Tachometers which are obviously AC Delco units; some having that same cylindrical box.

Google combine harvester

 

'40 I think.

I just used mine to show the flywheel rpm on an old International stationary engine. An engine like this has a flat pulley on the side to run a belt to a piece of farm equipment.

@Ebbsspeed. Most of the expensive ones came in a kit with multiple attachments. A wheel was included for measuring the speed on a belt. You simply multiplied/divided the reading by two or what ever the instructions said.

 

Not a true hit and miss, but the same idea.

A few I have bought over the years.

 

Must be a city boy. Have you ever seen a grain drill?

 

Why would you need to drill grain?

 

Surely you've heard of GMO (genetically modified organism)
Once a desired trait is identified, the grain drill is used as a means to inject the desired DNA into the seed.

 

From taillights to grain dna, you people need to get out more !!!

 

Bait, that is!
Haha

 

^ I’m just responding to the OP and another poster. I’ve been ignoring the other one for quite some time now.
Maybe if he was actually funny it would be enjoyable.

 

No I’ll feelings here, post what ever you like.

 

You need a grain drill to plant the grain for the combine to harvest or a corn planter. Yall need to get out and learn some stuff about where your food comes from. And it is not the store.

 

Some older Gleaner brand combines were powered by 292 straight sixes or 327 V-8 GM engines, that could be used in one of those homemade hot rods, back in the day.

 

Really dude? You actually mean grain is grown from the ground? WOW!

I had no idea, can you tell me where babies come from? Always been curious about that.

 

They come from combining two processes.......’drilling’ and ‘fracking’ (pumping fluid under pressure”......

 

What was the question again?
