I am delighted to say that several of these elusive Romside metal/tin windows were put up for sale on KT Miniatures website today.
Many a finger and knuckle got scraped on the metal hinges as one went about one's business of opening and shutting the little windows, during the course of some serious childhood imaginative play! Those little butterfly handles also had a tendency after much use to simply wear out and snap off.....but apart from all that - I still think they are wonderful, don't you?
These Romside windows are often referred to as Tri-ang windows, which they are most definitely not. Tri-ang windows are slightly different dimensions, square panelled and a different colour. All of the various makes of tin/metal dolls house windows are becoming extremely sought after nowadays, as they are far more difficult to get hold of - so unsurprisingly value is rising steadily too.
