Mini Brush Boar Hair? What was it used for?

I purchased this little brush at an Estate Sale and have been unable to determine what it was used for. I can't find anything similar on other sites. It is about 4" long. I think it might be badger or boar hair. Any info would be appreciated!

 

could be for sweeping crumbs.......or a clothing brush........
if it has a pin on the back..it's for a tyrolian hat.......
i can't see it well enough....

 

Thanks! I was also thinking of a clothing or hat brush. There is no pin on the back.

 

Methinks Milord's Man used this tool to ensure the his Master was de rigeuer.

 

Bavarian or Tyrolean hat brush missing its holder.

 

Thanks! I looked them up and I believe that is probably what it is!
