Whoever said, "gemach", having looked that up, yes that seems to be it.
Waves tot he Finchley people, I lived in Hampstead Garden Suburb and then Finchley.
I'll just add to the language by introducing some sign language.
BSL has at least three signs for 'Jew' or 'Jewish', the most politically correct and accepted you start with your hands in front of you, palms facing away and thumbs crossed, the hands then go down, out, up to represent the menorah.
The other signs are older and thought to be less politically correct, and sexist. One represents a beard and the other you make ringletts at the side of the head. I find when the discussion goes to 'orthodox' or 'ultra orthodox' I'm using the different signs in my head.
I watched 'strictly kosher' recently, I actually cried when the 90+ year old made his Bar Mitzva (he was in hiding during WWIIwhen he had his birthday).
Thanks again for all the information.
