I would greatly appreciate any help identifying this brush. It has B600 stamped on the bottom of the handle and other than that, there are no markings anywhere else on the handle. It has a badger hair knot that looks as though it has not been used and has no smell other than "old." The only reason that I am thinking that it may not have been used is that it does not appear to have bloomed. I have not done an exhaustive search on the butterscotch thread but I think that I may have seen one like this posted somewhere on here in the past. I will be glad to answer any questions that would be helpful to identify this brush.



Best regards,
Doug
