I'm excited that I just received a vintage Stanley 169 shaving brush and was able to confirm that it's truly NOS. I love using vintage brushes, but I'm especially happy when I'm able to luck into an NOS one so that I don't have to spend time replacing the knot before using it. I'm just going to clean this one up and use it tomorrow morning. The hair could degrade due to age, but I'll get some use out of the original knot.
Here are some photos.
