Scottish Box Iron, sad / flat iron

This scottish box iron is unusual in being made entirely of brass. It is in first class order, apart from a few very minor chips on the handle and one or two small old scratches on the body of the iron all of which are visible in the photos. When I first bought the iron the finial at the front of the handle was broken, I therefore had two new finials made, the old ones are included and are shown in one of the pictures. The iron includes the original slug, which again is unusual.
These box irons were thought to be produced as apprentice pieces by the trainee metal workers in the industrial regions of Scotland during the last half of the 19th century. Each iron is unique, as only a broad set of parameters were given to the trainees. However each iron successfully showed the makers prowess in all the various disciplines that were taught, such as casting, turning, screw cutting and finishing.
