Side pieces are removed from jamb
Top piece stays in place and stripped revealing original red oak
Sides are flipped, sanded, and reinstalled.
Door stops are stripped and reinstalled covering most of the nail holes. Cut, strip, and install some original casing you found being used as shim scrap under 1970's panelling - and you're in business! Not sure if I'll install a door here or not as was original - how do I know - well 100 years ago the builder left a note under the jamb which side the door was hinged and which way it swung!
