Brilliant! Thanks very much, Roslyn! Neatens was the answer I had in mind, from 'Neat' (pure) and Ens (as possibly in 'N' for nuts, but Bradfords confirms it. Must get a copy of Bradfords - would have saved so much time! Thanks again.
Elliemay - I am presuming 'N' can be an abbreviation for nuts, thus 'ens' for the plural.
