I'm not sure that I follow what you mean by "source".  The web site I 
provided a link to is a source.  If you mean where are these clutches used, 
most of this size are used in industrial automation.  Some can be found in 
large printers/plotters.  There are larger examples used as PTO clutches for 
lawn/garden tractors.  The cost of these is prohibitive.  I could burn up a 
couple dozen smaller clutches for the cost of one of these.  The cheapest 
that I've found is 200 dollars (US).  Even non-surplus small clutches can be 
VERY expensive.  I work in an industry where such clutches are used.  The 
cheapest is $180.  Any surplus dealer may have them.  You will have to pay 
close attention to how the clutch is constructed.  Some are purpose-built 
and are not easily adapted to our use.  Automotive air conditioning for 
example.  Some, like the one I provided a link for, have a chain sprocket 
input and output while the body is held fast.  Some have an input or output 
that is shaft mounted.  Some of these may be usable, but watch the shaft 
type, many use a hex or spline shaft.
