I must agree strongly with Alan Owen. The 4th and 5th Border Regiment badges had almost certainly gone by WW2. Very few Territorial units retained their distinctive badges beyond the end of WW1. Remember also the TA reforms which brought infantry units into searchlight or anti-aircraft units- far removed from their original functions - and requiring re-badging to RE or RA. I have always accepted that we said farewell to TA badges in their original form by 1920. I would be very interested to hear other informed comment on the subject. Regards to all. David
