Get a Grip!
My research tells me that this is a Flemish brass of Simon of Wensley, who was the rector at Holy Trinity in Wensley between 1361-94. He is shown in his mass vestments with a chalice on his chest. The brass is full length but I’ve chosen not to include all of it here.
Simon was rector when Edward III and Richard II were on the English throne and would have been a survivor from the Black Death
Apparently, the church itself has parts of it’s structure that date back to the 13th Century.
