Hi Dickson,
Yes, my attenuator board has the Rev C part number as you surmised below. However the exposed circuit traces appear to be gold plated.
The serial number of my unit starts with 1748A13xxx, so I think that it was produced fairly early in that product's lifecycle.

I think Patrick's attenuator board is the newer "03325-66523 Rev C" which used the relay made by Aromat (Japan). I think Aromat is being merged with the Japanese giant Panasonic.
It seems to me "Rev C" is a cost down version because it is not longer having the gold plated PCB.
