A brass combination lock recovered from a Welsh shipwreck has yielded its secret: ANCE. But opening the mechanism has left a more human question unanswered. Did those four letters mean anything to the person who set them?
In announcements on November 4, 2026, Amgueddfa Cymru – Museum Wales and Cardiff University reported that CT scans had revealed the combination. The museum associates the lock with the Ann Francis, an Elizabethan merchant ship wrecked at Margam Beach, near Port Talbot, in December 1583. This is a newly reported investigation of an old discovery, rather than a shipwreck found this month.

The museum’s own film below shows the object and introduces the investigation. It provides a useful distinction from our illustrated lead image: this is source material about the surviving artefact, while the ship scene is contextual artwork.
Looking inside without breaking it
Cardiff’s account identifies researcher Dr David Williams, based at its Musculoskeletal Biomechanics Research Facility, as the specialist who used micro-CT to examine the mechanism. The technique produced a three-dimensional view of its interior without taking the historic object apart.
Williams could compare the internal notches with the letters on the outside and identify the combination. The museum team then tested it and confirmed that it worked. Those are two separate steps: interpreting an image to propose a code, then checking that proposal against the physical lock.
Its survival is part of the story. Finder Peter Hughes told the museum that the lettered rings still moved readily when he recovered it. He found most of the associated hoard between 1996 and 2017, as storms and dredging exposed material beneath the beach’s sand. The museum describes this lock as exceptionally well preserved and stresses its association with a dated wreck.
An answer with clear limits
A working combination does not tell us what the lock once guarded. Cardiff says it was found near Spanish silver coins and two coin weights. A small chest of valuables is a plausible interpretation; documents or textiles are also possibilities. None of those possibilities amounts to identifying the contents of a particular chest.
The museum’s longer history of the Ann Francis adds an important complication to the familiar “untouched treasure” picture. Contemporary legal accounts describe people taking goods from the wreck, competing claims over it, and an inventory that included three chests with broken locks. That historical record cannot, by itself, attach this surviving combination lock to one named chest.
The same distinction applies to ANCE. The reported test establishes a usable sequence, not a translation, a personal message or a hidden instruction. An interpretation of its meaning would need additional evidence about the owner or the object. There is no need to invent one to make the discovery interesting.
The lock and other finds are displayed in Tides of Treasure at Swansea’s National Waterfront Museum. For now, the satisfying result is also a limited one: researchers have explained how to open a remarkable surviving object, while leaving its owner’s choices open to further investigation.
