colyn,
do know of the claim that the IIIf RD ST has a quieter shutter system than used in the IIIf BD or IIIc, etc.? When converted did your camera receive a new shutter? FWIW, I asked Don at DAG about this and he didn't buy the idea that the IIIf RD ST had a quieter shutter than other IIIfs or the IIIc. What is your experience of this?
respectfully,
thomas
