Zeiss Darkfield reflector and BF-reflector

Hello again,

Looking again for some parts for the Zeiss Universal/Photomic III - P/
N 46 62 63 - Brightfield/Darkfield reflector for the IL nosepiece and
for P/N 46 62 62-9903 - Darkfield reflector. Any sources are most
welcome, I found one, but they want USD 900 for one of them, which I
rate as crazy!

Kind regards
Georg Nyman

PS: Does anyone out there have a user manual of the MC-63
photomicrographic camera? I would be very much interested in it....
