Sam at BLAGEdward Fison Ltd, Dock St, Ipswich.
This was once the home of the company that became Fisons Ltd. It doesn't explicitly state it, but the Wikipedia entry suggests that 'Edward Fison Ltd' could have been used in the 1920s: https://en.wikipedia.org/wiki/Fisons.
If anyone knows more, do tell.
