Can anyone shed some light on this smock for me please? I bought it on E bay and the chap who was selling it reckoned it was from the 1960's. However it has velcro and a large plastic zip on it so somehow I dont think its that old. It has a brown nylon liningthat seems to have a rubberised coating on the inside. The buttons are the large green ones similar to those on the Falklands Parka and the extreme cold weather liner. The material seems to be ripstop fabric.
