I have an antique morris chair that's stuffed w/ horsehair. About 125 years old and still going strong. As for other hair for shaving brushes, I know my dad had an old shaving brush that he picked up in a yard sale before I was born (1951) that was made from sable. I used to watch him shave and he'd swipe my cheek w/ the lather. Even to pre-school skin, I remember it as one of the softest things I've ever felt. Don't know whatever became of it. I suspect he sold it to someone as I remember in high school he bought an Ever Ready boar bristle brush at the corner drug store, and the owner commented it was the first he'd sold in years. One of my nephews got the Ever Ready, I got several of dad's old Gillette Super Speeds and a couple adjustable Fat Boys. I passed some on to family members, and kept 2 Super Speeds.
