Many thanks for all the replies.

All that I have on hand at the moment are 740-031833 optics, so I can't
do side by side testing.  I have some 740-014279 optics on the way to me
and I'll check them out and report back what I find.

To add to the fun, I have some optics labeled as the 740-031833 part
number with and without the trailing -C

My first suspicion was that the two optics were designed for different
operating temperature ranges (CO vs DC), but the above part descriptions
lead me to believe that these are essentially the same optics
differentiated mostly by whether they are "sold for" EX/SRX or M/T/MX.
