In response to the query about which colour combination of pips relates to which unit, the National Army Museum archive really is the place to go. If you don't have a reader's Ticket, just write and apply for one they're free and are renewable every year. It gives unlimited access to the archive which is second to none. Just to complicate matters -have you noticed how the backing material on cloth pips varies from unit to unit ? That too is an example of the wide variety of colour combinations relative to wearing pips. Beware pips that are not military in origin - SJAB, RSPCA, Red Cross, Church Army, Salvation Army, Boys Brigade, etc. They tend to be chromed but some are gilt/brass. Regards to all. David
