Brass 'dust-busters' on the stairs?
I'm still in tthe honeymoon phase with my 1900 brick 3-story, which seems to be in astonishingly good shape, considering I'm the 13th owner.
When I first looked at the house I noticed these curved triangular brass pieces nailed in the corners of the first floor stairs. The first flight of the first floor staircase has them in both corners of all the steps, the second flight is missing most of them.
I'm assuming these are some sort of amazing labour-saving device for the mod turn-of-the-century housekeeper, to prevent dust from accumulating in the corners of the steps.
Does anyone know what they're called?
