I got this black S3 + Olympic 50mm 1.4 a few months ago on Ebay at a somewhat decent price. It's a beauty, and works perfectly, except that the rangefinder patch is weak and it's got the helical lens squeek. I just also bought the 35mm 2.5, which is absolutely mint.
Originally the previous owner of the S3 and 50mm lens had blacked out the white logo and text on the body and lens. So it was a little cheaper than it should have been. I was able to remove most of the black ink on the body and refilled it with white. But I decided to leave the lens alone since it would be too difficult to remove the ink and repaint the ring without taking the lens apart, and it seemed unnecessary anyway.
I believe this is an original black paint one, even though the serial number is earlier than the known "Olympic" serial numbers. There are some apparently out there, and this one has Nikon F parts like the Olympic version. I've found another one on this website that is really close to my serial number and is exactly the same:
