Have 4 interior doors that are solid panel-flat panel no design. These are possibly 35 years old if they are original to the house. I consider these in very good condition to excellent. Normally, I would discard of old doors and trim. However, I find in todays world a much better quality of wood and workmanship with wood years back. The doors had been painted about two years ago. I removed to install a different style door. I have 3 30" doors and 1 28" door. Each door has hinge cut outs, stop cutout and holes for handle-stop. I did toss the hardware on door as the brass was discolored and not worthy of a descent look. The doors are standard height.
I'm selling at 25.00 each or if one takes all 20.00 each. Will try and post pics.
