I have a tea cup and saucer that both have the same mark, though both are very worn. top is a KM (?), under that an L, to the left a gegr., or gogr., to the right 1834. possibly german?

Can i see the pattern on the teacup please

if it's german the gegr. is short for gegründet (founded) and 1834 is the year.

Yes as Fritz just said
