Indeed, Jewish history records the canon fixed by the ‘Men of the Great Assembly’ which existed 410-310BCE. The Council of Jamnia canon story is a Christian invention.

First, a niggling point, you do mean 410-310BCE

Secondly, please can you give a link to that -- there is no indication in what i have read (which is admittedly litte, hence I'd like to read what you have) that Jewish canon was fixed in it's present form before the Council of Jamnia

And again, the dates seem wrong from what I read that The Great Assembly (Hebrew: כְּנֶסֶת הַגְּדוֹלָה‎) or Anshei Knesset HaGedolah (אַנְשֵׁי כְּנֶסֶת הַגְּדוֹלָה, "The Men of the Great Assembly"), also known as the Great Synagogue, was, according to Jewish tradition, an assembly of 120 scribes, sages, and prophets, in the period from the end of the Biblical prophets to the time of the development of Rabbinic Judaism, marking a transition from an era of prophets to an era of Rabbis. They lived in a period of about two centuries ending c. 70 CE

Note that the date 520-70 BCE is for the whole 2nd Temple period, not for the Men of the Great Assembly. Jewish history records their dates rather precisely, naming each leader after them. Christian sources have their own reasons for altering dates.

Anshei Knesset HaGedolah

Anshei Knesset HaGedolah (Men of the Great Assembly) founded by Ezra in approximately 520 B.C.E., this institution of Torah Sages led the Jewish People at the beginning of the Second Temple Era (ca. 520 B.C.E. - 70 C.E.). It included Mordechai and the last of the prophets Chaggai, Zechariah and Malachi.

Among the accomplishments of the Anshei Knesset HaGedolah were finalizing the contents of the Tanach,the 24-Book Hebrew Bible, instituting the Shemoneh Esray Prayer (recited at least three times daily, and ultimately to serve as a substitute for the Temple Sacrifices), and the enacting of many Laws to protect and bolster the observance of the Torah Commands.

According to Pirkei Avot (1:1), they are the fifth link in the Chain of Jewish Tradition: 1) Moshe receives it from Sinai and teaches it to 2) Yehoshua to the 3) Elders to the 4) Prophets to the 5) Anshei Knesset HaGedolah, at the end of the Biblical Period (ca. 520 B.C.E.). Pirkei Avot (1:2) also identifies Shimon HaTzaddik (Shimon the Righteous) among the last of the Men of the Great Assembly at the beginning of the Talmudic Period (ca. 200 B.C.E.)...
