The makes has been identified by an impressed "Ridgeway" which indicates one of the early Ridgeway firms, possibly Job ridgeway, George ridgeway or John and William ridgeway The border vignette is shown as Border vignette A This volume and the other 5 in the series are available from Reynardene publishing UK at a very reasonable price you should consider investing to see the other named patterns in the series based on William Angus's Seats of the nobility
