Regarding the chaning of position, you do need to loosen a tiny screw first before you can twist the bayonet. The bayonet is locked so I wouldn't just twist it. There has been one black Rolleilux that went on the auction site and I have a picture of this on my site. You can see it here: http://www.siufai.dds.nl/Rollei_accessories_1.htm (some where in the middle) Since it seems to be bigger then the regular hood and the bayonet is very different than the regular Bay II I assume that this is a special one made for the 2.8A. It does not make sense too to make a Bay II Rolleilux model since you can buy a T meter and add that your E model 'flex to get metering.
