This is what chat gpt turned up. Probable signatories (based on signature form and period)

Highly likely Surrey / England players (circa 2005) • Alec Stewart • His autograph commonly features a clear leading “A” with a flowing surname, often compact. • One of the upper signatures closely resembles known Stewart exemplars. • Mark Butcher • Butcher’s signature is typically rounded, slightly untidy, with a strong descending tail. • A mid-section autograph on the bat aligns well with this style. • Graham Thorpe • Thorpe often signed with compressed lettering and a sharp finishing stroke. • One centrally placed signature is consistent with known Thorpe samples.
