Hi, I Bought this Tunic a while ago at a military fair for the princely sum of £30. As far as I can tell it must be of some age as its lined with a sort of cotton material and is all hand stitched. To begin with I thought it might be some sort of First World War dress tunic, but from what I know the buttons are not the standard Royal artillery type. I have seem tunics similar to these before but in different colours, however it does look to be of the same era in the way it is cut in my opinion. However These are just guesses as I do not know am awful lot about Tunics of that era.
As always If anybody has any ideas on this one they would be well revived as I'm stuck to be honest
