Hello, A question for you historians out there. I read somewhere that the SAS were issued with windproof smocks the same as DPM smocks but in olive green rather than DPM back in the 1970's I have found a seller on EBAY with loads of SAS smocks in green BUT with taped buttons which are not exactly 70's ? I am not referring to the wartime smocks etc but an SAS smock in the same design as the "smock, windproof, artic" but in olive green as opposed to DPM. Any opinions ? What should I look for on the label to check if genuine MOD kit ?
