Not sure of age, but these dark stained fir full lite doors looks to be in good shape (like it was used under a wide eave or overhang). The insulated glass looks like it is not fogging. The door is currently set up for use in an outswing application, but there is no threshold on the jamb. The doors and jamb use J hook weather stripping. There is no key for the nicely aged brass knob set and deadbolt. This is one of the full lites with a very wide bottom rail, which makes it a good option if you need to cut down a door. I do note a crack at the top of the hinge side stile on the active door. I'd guess it's been repaired, but I'm pricing it assuming you'll have to glue and screw it. Price reflects condition.
