Instead of a mirror that swings up there is a prism assembly in the light path that splits part of the light up to the ground glass and the rest of the light continues back to the focal plane. AFAIK all of these were custom made by camera repair shops although it's possible that Leitz made some too. I don't think there are any catalogues showing them.
