i have wooden casement windows at the dollhouse which actually opened with total ease ( wonder of wonders, miracle of miracles) they have the latches and the hinges are in perfect working order, but there is no "crank " like i am used to seeing on this type of window.
do they just latch back to the wall? i checked on the sashes and it doesn't appear that there ever was anything else there that has been removed, or broken?
