Weight type object found - what could it be?
We have a c.1880s pseudo-Victorian that we've been restoring after some years of neglect. The yard is always turning up stuff between the drought and then pounding rain. Each time it rains we never know what we'll find. 99% of the time it's 50 years of buried trash, occasionally it's some interesting metal piece, though nothing as exciting as my neighbors who some years ago found a bayonet from the Alamo (we're within the area that was the encampment for the Alamo) or the other neighbor who found a gold bar...
Anyway, so while digging this weekend I found this weird object. It appears to be the same material and weight as the window weights (original wood, double hung windows), but we're taken apart all our windows and haven't seen any such object. If it's not obvious from the pictures, it's flat on one side, sort of dome shaped on the other. It looks like it has a hole down the middle (for a rope?). I realize this is probably not very exciting, I'm just wracking my brain trying to figure out where this may have come from.
Any old house people have any thoughts?
