Below the museum number (inked over varnish onto the vessel in the 1960s), may be seen a fainter 23 over 462; this indicates the excavation year as 1923, and the find-place as no.462 = tomb 462. The vessel is late Old Kingdom, about 2200 BC, explaining the other more recent marking ‘VI QAU’ (VI for Dynasty 6, roughly the period in question); the excavation report for the 1923 dig at Qau confirms the presence of late Old Kingdom pottery in burial 462
