And, I spent the morning 'touching up' the previously stripped wood trim along the stair stringers. That is to say, I spent the better part of the day scrubbing paint off 2 pieces of wood. They look good, though:
A couple of uh-ohs so far.
1. The animal room door trim appears to have been stained a touch lighter/redder than the rest of the trim, supporting Ken's claim all along that that room's footprint was somehow altered. Perhaps it was attached to the master bedroom, like a nursery? We don't know, and the floors and ceilings aren't making it obvious. Though the door might have been moved, I think the overall floorplan upstairs was probably similar to what it is now - we found a very similar upstairs plan in an old bungalow plan book.
