Every Xmas back in the early 60's our boss at work Mr. Coker at USDAW in Newcastle on Tyne used to buy us girls in the typing pool a box of Terry's 1767, so named presumably because of the year Terry's came into production. They were fantastic but very expensive, also difficult to come by. I think very few were made and were snapped up quickly.
Hello to Pat, Shirley and Susan, past employees if you're out there and read this!
