I know it's a long shot, but I'm hoping someone knows/can identify (or at least can point me in the right direction in terms of search terms) the style of this cap. I'm hoping to find a router bit/bits that I can use to duplicate it. I'm not sure if it's original, but it's from a house built in 1890.
I've done a bunch of searches, but I feel I lack the terminology to look for the right thing. Is there a term for the three "stairs" at the bottom? Any insight anyone could provide would be greatly appreciated!
