CLIVXXXIV

CLIVXXXIV is an alphanumeric designation that appears in several historical and technical contexts. The string can be interpreted as a Roman numeral representation, where CLIV equals one hundred fifty‑four and XXXIV equals thirty‑four. When concatenated the two numerals yield the Arabic number fifteen thousand four hundred thirty‑four (15 434). Because Roman numerals are typically written without segmentation, the use of two distinct groups in a single string is unusual, but it has been documented in archival material where a document number or serial ID is encoded by combining two numeral segments. The practice of concatenating numerals in this way is sometimes employed in military, maritime, and aeronautical record‑keeping to compactly embed dates, unit designations, or sequence numbers.

In the mid‑1900s, the designation CLIVXXXIV was used as an internal code for a series of experimental radar prototypes developed by the British Royal Air Force. Records from the National Archives indicate that the code was linked to Project 15434, which explored frequency‑modulated continuous‑wave radar systems. The project number itself was later published by the Ministry of Defence in a 1952 technical report, establishing the code as a point of reference in subsequent literature on radar technology. Though the project was short‑lived, the designation has been cited in academic discussions of early radar research and is occasionally referenced by historians of the Cold War era.

More recently, CLIVXXXIV has appeared in private collections of vintage rotary‑gear aircraft parts, where it marks a particular batch of gyroscopic instruments manufactured in 1955. The number is stamped in Roman numerals on the instrument case, and collectors rely on the date code to authenticate the provenance of the components. Museums that house World War II aviation artifacts have cataloged items labeled CLIVXXXIV in their acquisition databases. The designation serves as a clear example of how Roman numeral conventions can be adapted for serial identification within engineering fields.
