Must be a typo, but it does happen.
Old man's story but............
In about 2004 I fixed a power supply for a 486 computer for an avionics company. They were prepared to pay a massive amount.
They said it didn't matter because the computer was part of their system and due to their strict procedures and it was too difficult to replace.
They even had the serial number of the power supply documented, so they were stuck.
In that job if the original fan was unobtainable, I would have bought one at such a price and they would have paid for it.
