And possibly date them tks
The speedometer and vacuum gauges are out of a car.
The Davtron Model 920A is a Digital VOR display, and could be out of almost anything, as they were after-market AFAIK
Likewise, the hour meter could be out of almost anything - are there any part numbers on the data plate?
As for the oil pressure gauge, its hard to tell - again, a photo of the back of it with a part number would be helpful.

The oil gauge has nothing I can see on the back side. The flight hours one backside I's M-5614.
The hours and tenths back side is the AwH back. The vacuum back us the 355a back. Thanks for your help

As gumbyk pointed out the Smiths speedometer is from a British car and the vacuum gauge is automotive aftermarket from auto parts store. The hour meter could be from any piece of machinery, airplane to stationary engine. Basically anything that requires service at specific hours of run time.

Okay thanks for the information. I got them from my Grandfather. He was a mechanic at Wright Field back in the day.There is huge socket sets and some confusing tools

The vacuum gauge could have been bought locally near W-P to use as test equipment but I suspect your Grandfather had a British car with that speedo and he installed the vacuum gauge in it. The others, he may have removed from aircraft and installed replacements.

I think the automotive gauges might have came from a ground support equipment if your grandfather was working at Wright Pat

I'd like to see the ground equipment the 120 mph speedometer came from.

If that speedometer was used on GSE, it was more of convenience rather than function. I've seen tugs with speedometers that peg at 80 mph, no way they would ever go that fast!

For a while I had a Fiat 1400 with metric instruments and wowed those unaware of Europe with the 140 m.p.h. (86 kph) speedometer.

Not using math every day, what I meant was the odometer topped out at 140 kph which is 86 mph. The old beast could not achieve close to that, but tried it's best. Many funny occurrences while owning it.

I've worked at a few places where the GSE mechanics would replace instruments with what ever they can get their hands on. Many civilian aviation operations really skimp on GSE maintenance although I've seen some mechanics do some creative things to GSE, like put an altimeter on a tug's dashboard!

The US introduced ZIP codes in 1963, so the Davtron meter can't be any younger than that.

The Davtron was build between about 1984 and 1996, when the 903 came out.

Thanks for all your help everyone
Yup, our aircraft tugs had speedos measured in Ks and the upper limit was beyond 60, but now way you could get them faster than about 30 flat out. I think I got one up to 27, 28 down the taxiway once! One of the guys drove one through the drive through at Maccas down the road from the airport one night...
We had one that had a four speed gearbox that had the gates for 3rd and 4th blocked off with a welded plate on the shifter. 5 minutes with a grinder and we'd more than doubled the top speed!

Don't worry, we pretty quickly found out why the top two gears were locked out... Drop the clutch in fourth gear and it would wheel stand!
