David Richardson seems to be an unending source of rare material. Here is a catalogue issued by Pathex in America.

David Richardson has been at it again. This apparently does the same job as the cone-shaped Pathé Magnifier lens. The third pic shows a Pathexor Krauss lens, one of two better-quality lenses available for the Baby, the fourth other, the Hermagis.

And this is more stuff about the water-cooled condenser set-up. It seems to have been made by a company called Mollier, and come in two versions. First was a new lamphouse to give a brighter light from a new lamp and condenser lens, tho'

the voltage and wattage of the lamp seem a bit unclear. The second or "Super" version had the water-cooled jacket. Partly because it's not always clear from my knowledge or not of technical French, and partly because all we have to work on is an extract from a French equivalent of a Wallace Heaton Blue Book, everything else is less than clear, too. The text seems to imply that there is an automatic voltage reduction for still frames, to prevent heat damage to the film. However, looking at the pic shows no way this could happen and Dave can't see how either, despite having got one of them. We shall have to find more info.
