Hi Richard, Sorry no markings on it...I thought i could get some idea of age from the 5 point label on the front. The strange thing is the duke of york standard has a three label with azue ble anchor on centre,but this medal has a five label with red anchor on centre,i cannot find it anywhere, All i have to go on is it came to me from a relative who was born in russia in 1886,served as a sjt in the middex reg during the first war,then in the rnvr during the second world war....then as if that was not enough went on to join the allied control commision, That is why i am trying to get as much info about this man as possible before he gets lost in time like so many others, Sorry if i've bored you but thanks for your help anyway
