Help identifying pottery mark? There is a good mark hard to read.

Hello

We could use some help identifying the pottery mark on the bottom of this mug.

There is a good mark but it is under glaze and hard to read. We were hoping someone has seen it before. we kind of think the second word on the top of mark is "Bros." but are not sure about that either.

Thanks for Looking! Any help would be greatly appreciated.

Best Regards
