Experts have cracked a four-letter code to open an ancient padlock from a shipwreck off the Welsh coast using modern scanning technology.

The 400-year-old brass lock was discovered by metal detectorist Peter Hughes in the sand near Margam in Port Talbot, in 1999.

It forms part of a wider treasure hoard from the Ann Francis ship that was caught in a storm on 28 December 1583 on the way back from Spain. Its cargo was hidden beneath the sand for centuries.
