Can you help me to identify this large plate/bowl

[baihar]

This is a large (11 1/4") heavy platter or bowl.  It has some rust and glaze contractions.  I have owned it for about 40 years and purchased it as an antique.  Any help will be appreciated.

Looks quite a nice dish , Republic period circa 1910-1920 maybe .

Looks like early republic to me.
The bottom mark says  "??    ????  ??", (or "made by Detai Porcelain Store, Peking").
