My mother has a Shaw Walker filing cabinet from the 1970s. When doing some renovations, she asked the workers to take the drawers out. One was left in. We are completely dumbfounded about how the drawers go back in. We’ve studied the one drawer that remained in place. We think the brackets may be in wrong. My father sold Shaw-Walker filing cabinets for years, so he’s probably rolling over in his grave! He didn’t pass down his talent. Could anyone possibly help? Thank you so much.
