Original Rococo French mahagony bed. ??

Please help !! I had purchased a beautiful piece from an antique store and do not know very much about it ... I have done research to find out it is a Rococo piece it is mahagony wood it is a king size as they say , but I'm not sure of the time period it rasies a few questions cause when i had took it home to clean i had relized in the back of head board and foot board they dont put furniture together like that with dawls !! Please i am looking to find an answer have asking an antique dealer which had told me to look into it .. It seems like you have a piece of an original Rococo dating back to the 1800's ...
