I have a Nikon FA that needs mirror foam installed. Who replaces mirror foam? Years ago, I sent several cameras to a nice lady repair person to have mirror foam installed, and she did a professional job. Anyone know who she might be? I think she has an ebay user name of "marmot" something or other, but when I search ebay for sellers, "marmot" doesn't show up for me. Thanks for any help/recommendations.
