JEFFREY L. - Hello, friends; thank you so much for this forum!! it's helped me identify a few i was obsessing about. Pete, i'm curious too- i have 2 beautiful pieces with that incredible matte glaze that's a joy to hold. one turned out to be late 20th cent
Japanese the other numerically marked over under as this (but stamped) is German
but I wouldn't rule out the lower character as an initial-or perhaps the year? sorry-wish i could be more help.
