The bronze guns were discovered by both the Chorley Sub Aqua Club and the Merseyside Sub Aqua Club in the same month. Under the direction of Peter Davies of Liverpool University and the Merseyside Museums, the artefacts were rescued from the site before they were lost to looters. The collection was conserved by the Liverpool City Museums Conservation Department and the Merseyside Museums now have over 1,500 objects from the "Mary", including cutlery and jewellery. A model of the "Mary", built by Des Newton is also on display.
