Diff Stamps

["Hill, Stephen M EDUC:EX" <Stephen.Hill@gems7.gov.bc.ca>]

Hi Rich. I came across and old email where you said that on the TR6 diff
stamped:
CP = 3.45 ratio
CD=3.7 ratio

Do you know other codes?  I am chasing down a 4.1:1 , and knowing the full
range of codes would be helpful.

Thanks.
