Just love engraved bells! This one was made by Richard Sizer Ltd. Hull. It is engraved boldly on the bell together with FIRE BELL. Unusually the handle bears a label with a logo for GTE 82-90 Seymour Place W! London. Richard Sizer began founding in 19 century but I know nothing else about them. Still searching. As for GTE. I'm still trying to track them down. The bell has a diameter of 6 inches.
