We lived in London when i was a kid, and my dad used this shaving brush. He bought it in the late 60s and gave it to me when I was in high school. I have used it on and off for 20 years. Here is a photo of it next to a Vulfix 2235. It is really soft, and still lathers wonderfully. I believe the writing says "N4" and underneath it either "badger" or "england". Any clues?
