WOW, that was cheap. I have one like that but for that money I would have bought another one. The only TRUE GRISWOLD one of these says 'Erie, Pa' on it and it has the pattern number 180 on it. When Griswold operations were merged with Wagner the pattern was modified by take the 'Erie, Pa' off and replacing the number 180 with the 310 that you see here. And then they later made ones without the Griswold name. These were made by Wagner and what I call 'partially marked', but very clearly former Griswold lettering. Hope this does not muddy the waters too much. :-/
