Of obscure parentage, Salter had established himself as a merchant in the Cornish port of Fowey by the early 1430s. His business appears to have expanded rapidly. By the end of the decade he maintained an account with the London branch of the Borromei bank, and even by that time he was probably trading in commodities such as woad and wine with alien dealers.
Otherwise, Salter’s career was unremarkable. Although he never used any of the wealth he gained in his trade to acquire significant estates in a bid to enter the ranks of the landed gentry, he was not without connexions among the landowners of the south-west. His only child Elizabeth married John Herle of Prideaux, a cadet of an influential if relatively newly-arrived Cornish family. Salter himself formed an association with Sir John Arundell II* of Trerice, for whom he acted as a mainpernor in 1453.
Like other customs officials both Salter and his colleague Vincent Pitlesden* found themselves obliged to advance substantial sums of money to Henry VI’s struggling government in the early 1450s, but as opposed to many of their fellow creditors they, on account of their official positions, had no trouble securing early repayment.
The date of Salter’s death is not recorded, but it had occurred by early 1474, when his widow was engaged in litigation over the execution of his will. His sole heir was his daughter Elizabeth Herle.
