If one looks long enough they get to see niche skill sets slowly evaporate as the world deems those skills unnecessary and businesses move to cheaper or perhaps better ways to do things ... more often though their product is not going to last 20 years like it might have once deemed necessary due to the disposable nature many societies have presently become used to. Pull apart the average old hydrogen gauge (laboratory or those used for welding) from the 70s or 80s and they were still fairly decent, (early gauges from the 60s I've pulled apart were solidly built, lots of metal matching to counter corrosion etc) ... however what was retailed in Northern Australia by the late 90s were utter rubbish unless I would presume the customer insisted on an imported one from the States or Europe and the customer paid a huge premium. The expertise to build a function and long term working hydrogen gauge was lost or considered not necessary ... and putting ever so slightly different seal materials in a merely essentially identical to an oxygen or inert gas gauge, (but with lf thread) might get it sold ... but never a repeat purchase.
