Toyo Modular System.
This 'entry-level' view camera was introduced 1984, and replaced
by a later version, the 45CX (with minor changes) in 1998. The 45C
view camera provides a full range of front and rear movements. It has
a revolving back, and accepts a great array of Toyo and other accessories.

(I have had this camera for quite a while, although it is not something
which I pull out of its large aluminum case everyday.) Some recent images
from this camera can be found HERE and HERE.
