No prize yet? I am leaning towards Culmac as the nearest similar looking brush I have observed with a similar shape. If not Culmac then Rooney seems to be a more likely candidate to me because of the printing on the brush and the Ivory imitation. The brush has turned Browninsh with age but not yellow. Makes me wonder what the handle material might be? BUT, what should IMHO, to someone, an "expert" perhaps, decide the manufacturer? I should think it would be the number 884. I haven't a clue really. I got the brush as an addition to what I bid and own on the big Auction site. And, this 884 brush blew that one away. I Used the brush for what I think is the first use and it is simply a fantastic small high quality brush. No shedding at all which surprised me. Very little effort to lather profusely. Much better than a Wee Scot, but the badger knot is simply a nigger knot and a much better grade than is in my Wee Scot best badger brush. 3 lather applications is easy with this one. I would definitely like a Simpson Keyhole or Persian Jar of this quality. And That I have not come across yet. At least not one I can afford!
