Vintage Jumbo Teacups and Saucers, burgundy with gold, crosswords, Lettering

Vintage Jumbo Teacups and Saucers, burgundy with gold, etched crosswords on saucer, different type of lettering on teacups. I have done lots of research and could not figure out who the maker was although by the markings they seem to be made pretty early. I could not find a exact match although Britain's early markings were similar. The size of these teacups we're hard to find a time period. They are in beautiful condition for their age no chip scratches or dents. there is some wear on the gold on the inside of the rim as seen in photos. Saucer 7" diameter Teacup 5" depth 4" opening 2.25" Bass
