Cleaning of the timbers has led to the discovery, on the planking of the outer hull, of a series of marks deliberately scribed into the timbers. These appear to be either individual shipwrights' marks or instructions for the positioning of planks or fastenings. The conservation team is hoping that a pattern will emerge as the recording process continues. During the summer of 2007, the cleaning of barrel-top fragments revealed merchant marks. Some of these may resemble known marks of merchants from the city of Bristol, but this is not proof that they originated there.
