A1 parallel ruler/drafting board, stand type. Used by two generations, but no longer needed, so I'm selling it. It's well-worn, with scratches and dirt, but the ruler moves smoothly and there are no dents that would interfere with drafting. The manufacturer and year of manufacture are unknown. It also has a light, which I will include if you wish. Please feel free to comment if you have any questions. Thank you. #draftingboard #parallelruler #A1 #standtype #heightadjustable #withlight
