I think I remember reading once that the names of the makers of the figures of the terracotta army are also recorded on their work. I suspect this is so they could be held to account - I suspect the First emperor of China did not have a great reputation for leniency in the event of poor workmanship.
Luckily, the workforce of Purdy paintbrushes live in more enlightened times, and anyway the paintbrush looks perfectly fine to me - a link between the craftsman who made the brush and the man about to use it. In this case Hodmandod Senior. No excuses.
