What camera is this?

[fsphotography]

Hi,
I received this camera as a gift, but what is it?
There is a brass plate attached to it that claims that it is a ''Sanderson''.
It looks to me like a home made name plate.
I have hunted high and low and cannot find a camera that has the same features
and fittings.
The bound corners and joints suggest to me to be a tropical version of whatever
it is.
The metal fittings are a combination of mostly nickle plate,that has some kind of
yellow varnish on it, and brass.
It is a triple extension with rise and fall front with tilt,no swing.
The bellows are leather with what looks like a silk material coating, grey in colour.
The corners are reenforced with burgundy/maroon leather.
There is no lettering or wording on the camera other than the fake? name plate
and the numbers on the extension scale metal strips. Can any one help? Frank from Downunder.
