Hi Bevan,
Your "Sea & Shore" brand was introduced around 1898 by W A & A C .Churchman of Portman Rd, Ipswich. This was a very old Tobacco & Snuff manfacturing company first established in 1790 as Churchman & Son. They took over Hubbard & Co in 1895 and in 1902 became a branch of the Imperial Tobacco Co Ltd. Your "Sea & Shore" brand were short lived according to records. I thought I had a photo, but can't find it at the moment.
