Thank you all for your answers.. escutcheon is the correct word to use for it and what I need.  I think it is perhaps the smaller version but just not sure.  The screw holes in the case for it are very close to 1 3/4" center to center and the opening for it in the case is 1 1/4" high by 1 3/8" wide.  There seem to be a number of ones available for either the model 60 or 38 but very rare to see the model 66 version for sale.  Oh well.. just have to keep looking I guess.
