Your safe, young man, appears to be a Phillips & son. Circa 1890-1910.
At the moment, I too am renovating an almost itentical safe. Mine has a double drawer and additional central shelf support.
Mid range Phillips safes used the unusual round back pan fastnings on a ¼″ treaded rod.
At some stage, i will be showing images of its restoration.
Good luck with yours.
Regards
Russell
