I have two old-fashioned metal mechanical pressure gauges. One is Presta, and it stays in my "touring" toolkit, I use it if I want to know the tyre pressure when on a bicycle tour. The other is Schraeder, I use this to test tyre pressure on hire cars and vans, because sometimes the pressures are way too low. Both are at least 45 years old, maybe older.

There are pressure gauges on the two SKS stirrup pumps I have, one pump is wide barrelled with a Schraeder fitting and used for motor vehicules, my wheelbarrow, and anything else with Schraeder valves. I take this with me if I go on a long trip with a motor vehicle, it once allowed me to detect a slow puncture and get it repaired at a convenient time. The other is more narrow (easier to reach a high pressure) and used for my bicycles. I also have an electronic pressure gauge, if I want a more precise reading I use this, mainly for my 16" Brompton bikes, where the loss of air when removing the pump head sometimes gives a significant pressure drop compared to the pressure shown by the pump.

There is also a pressure gauge on the Lezyne mini foot pump I take on long tours, but this isn't accurate.

Once-upon-a-time I had a SKS steel barrelled track pump. It and its gauge worked fine. Then I found myself with other bikes having schraeder valves. All went well until it didnt. After the pump valve head wore out I bought another with a valve head that promised the adapter would work between schraeder and presta. But it never did. That,or it was me! I still keep and use the SKS for my presta valved tyres but not for schrader,story 293 pages long.

I then bought a  Zefal steel barrelled pump with magnified gauge to use on my schrader valve bicycles. Still,what is going on? Altho my sight is ailing,by the time I look to see the needle on the gauge to rate the tyre pressure,by the time I have registered to needle and bar pressure the needle has fallen back to a tyre pressure I know it cannot be. Thus,wanting a bar of say 5,the pressure is 2 then up to 7 before falling back to say 3. There seems to be no stability wherein I can gauge the reading. The needle on the gauge seems to appear to be very fickle and indeterminate in its reading leading me to have little confidence in the tyre pressure.

I think I have been inflating tyres for some 60 years, so I dont know how I have found myself in this current condition.  I wonder if I have become more particular in wanting an accurate and reliable tyre pressure reading,or whether the equipment I am using has become more....throwaway?

Cheering news indeed.

thinking of you Matt get better soon buddy.

anto.

thats a beauty enjoy it.
dan will no doubt let you know what all those numbers mean.
i doubt its a 59cm frame  58 top tube.
