Note the date! 1962 oil burner and boiler and still working today and near original. "The Economy of Quality" How appropriate, - buy a boiler and never need to replace it in a lifetime.
Circulating pump still going from 1962 with no isolating valves.
The oldest oil boiler I've seen was installed in 1965 and they were saying that it was 2nd hand then and had been donated to the rugby club.
Unfortunately when I got called out to it (it was there biggest game of the year, a local derby and the winner got promoted) the boiler had turned into a sieve and the burner was flooded they asked if I could fix it?
