I found this sad, very vintage old brush in a small-town antique store recently. It caught my eye because it's a very solid metal brush handle and the band across the middle appeared to be brass, but it was hard to tell because all of that black was obviously caked on shave soap and everything else that it may have come in contact with. Actually, it cleaned up much better than I had let myself hope, so now I need to order a new knot for it... appears to be 24mm. After cleaning and polishing, it's more of a silver color than I expected since I had expected it to be brass. Maybe it is, but I just can't tell. It doesn't feel like cheap pot metal , it's slick and heavy. If anyone has an idea what it's made of, tell me what you think.
