Window cranks are old they are about 7 1/2 inches long the long arm the short arm is independent of the long arm I believe it is truth hardware and she wants to replace it with something more modern. She wants the white housing with white cover and how the crank arm folds into the cover I believe this version is all one piece the arm and the crank. So the whole mechanism would have to be replaced the crank housing and the crank operation along with the arm. I can provide more photos. We will be needing 45 total along with new lock levers but thats a separate issue looking forward to doing business.
