To clean the Vaseline off of the filter glass, simply remove the glass from the filter ring (if necessary - use an old UV filter and it's not necessary) and immerse in isopropyl alcohol. Swab with a lens tissue. Any MF examples that I may have will be amongst my MF archive which is not easily accessible now as it has not been digitized. Here are some examples of the Zeiss Imagon lens and a 35mm derivative of mine. The portrait was taken with a Zeiss Planar lens in Arri mount adapted to Nikon F - not with a Imagon.
