Hello all Thanks for your comments Andy. You are probably correct in saying this style of window is unlikely to be found in this type of architecture. I should have said that this little row of Terraced housing is very much an experimental piece. It was the first time that I had used Linka after having found the moulds at a car boot sale a month or so ago. So I am trying out differing methods of construction, plasters, glue, joint filling and painting.
