What I love about living in an oldish (1902-4) house, despite how battered and altered over time, is how you can find little indications of how it was in its infancy. Nothing very dramatic, like uncovering a hidden room, or a large expanse of wonderful early wallpaper; this isn't that sort of house, but just teeny things.
This little keyhole cover - more grandly termed an escutcheon - had to come off in order to fit the new shower room rim lock and salvaged door knobs.
It's a humble object, made of thin metal, probably costing a penny a dozen in those days.
I shall clean it up and use it elsewhere.
I could see that the door was once painted green, over its original brown varnish. That's the sort of small discovery that delights me.
