Thanks Bryan for that information.
So the job title could possibly be an early name for a make up artist in a theatre (say) or it might just refer to someone who worked in a factory that produced the Leichner products ?
On the “Google” link it does not say on the English pages where Ludwig Leichner started his business in 1878 but it does indicate that the company registered its name in England in 1929.
There is ,however, a link to a German web page
http://www.leichner-kosmetik.de/index.htm?http://www.leichner-kosmetik.de/xaranshop_28.htm and this appears to give a lot of information about him.
Sadly, neither I nor my computer can translate this page but we can pick out certain words like Berlin and Paris. We cannot find any reference, though, to Moss Side.
This may suggest that there was not a factory producing Leichner products in that area (or, indeed, anywhere in England). In which case, the more likely job description seems to be related to using the products rather than making them.
Unless anyone can fault my logic, I will proceed for now on this assumption.
