Hi Rick,
They are all basically the same mic, but the SD is the one Paul Butterfield
used to use. It has an on and off switch on it, and Norton Buffalo has one
of these with a volume control in place of the on/off switch.

Not to mention that the D in SD means "dual impedance" which allows you to
set the mic for high impedance. I´m not shure :-) if the other models can
also be High-Z.
S should mean "switch" (on/off)
L -> low impedance
H -> High  "
D -> Dual  "

Check their manuals:
