No photograph so sorry did not have me camera whilst shopping with the Mrs but spotted a WW1 period helmet ,leather liner and chinstrap , helmet has a turned rim but appears Great War , the colour is a medium blue with a painted badge in yellow of 2 crossed rifles above the number 11 , the shop owner said it was Great War Portuguese Expeditionary Force ? , many years ago I had the fluted style but this type is new to me ,sorry for lack of photograph ,the asking price was 200 euro ?
