Identify this telephone?

Hi all
I’m trying to identify this wall telephone? Does anyone have any idea who made it, what country it’s from, etc? It’s actually part of a prop from the DrWho TV series. This telephone appears on the inside wall of the Doctor’s TARDIS. My builder’s club is making a TARDIS and we’d like to build a replica or find one but without knowing anything about its origin it’s difficult to find any of the parts. We can easily make the wooden box but we’re trying to source the brass parts if possible or get as close as we can.
