This is the dapper Fifth Doctor (Peter Davison) as he appeared at the end of the Black Guardian trilogy, in the episode 'Enlightenment'.

The hand-crafted figurine has been cast in metallic resin and painted by hand, and features the Doctor in his cricketing jacket and jumper, striped trousers, and even includes little details such as the question marks on his collar and stick of celery on his lapel.
