Question about an estate sale find

This brush was found inside a Neiman Marcus mens grooming kit with clippers, etc. for $10. It is a Thater that Neiman Marcus obviously decided to put in the kit knowing that Thater is high end, as is most useless crap from that department store. The deal is that I have lathered this thing probably 20 times..........and it is scratchy as HEYAL. Maybe I am just used to my synthetics and broken in boar brushes. I know pure badger can be that way, but I didn't think Thater would, "Slum (lol)," and make a pure badger brush. The only thing I can find that even closely resembles it is a Thater 4342 and that one is $40 and says it is best badger. Anybody familiar with this brush? I am about to put it on BST with my Merkur 39C for a $50 price tag with shipping lol.

Nobody? Well BST it is then.
