There is no mention of an S.J.Richardson in the Wrightsons 1815 or 1818 directories. (Aidan – I just had to correct that from 1915 & 1918 !!) . A bit off topic, but while looking I did find this advert (no apparent listing in the directory, just the advert) . It is a very bad reproduction. Possibly looking at a real copy of Wrightsons would make it clearer what exactly Richards’s Magazine is. Anyone else come across it?
