The service record is available on the pay site Ancestry. It may assist you to know that the address given for him on the "first payment of pension" record is 16 Isaac Walton Rd, Tillington, "Stratford" (must be an error for Stafford).

Earlier records show that 16 Izaak Walton Street, Tillington, Stafford was his parents' address.
