A Royal Navy flotilla provides a technical-source example. Official equipment records say that some vessels lacked the circular plotting display that required a continuously rotating radar. Their operational descriptions nevertheless sound as though they used that system. A jury-rigged installation or unofficial procurement could explain the discrepancy, showing how working practice can expose gaps in formal equipment records.
