I've been making good use of the British Postal Service Appointment Books on Ancestry to track down a cousin from West Yorkshire. However, I was wondering if there is a guide anywhere online for interpreting the job abbreviations therein, or indeed whether we have any retired postal workers from the old GPO who might be able to translate them into plain English? 'W'less' and 'P'man' are easy enough, but what is a 'U.S.W'? Something sort worker, perhaps? 'S.W. II'... how does that differ from a 'U.S.W'? And early in my ancestor's career, he was a 'LRNR'... 'Learner'? I daresay the Postal Museum would have the answers, but thought I'd try here first before emailing.
