50s ish swimsuit. Can anyone help on the brand?

Hello! I recently accquired this lovely wool swimsuit in perfect condition and I was wondering if anyone may be able to help me with who made it. The swimsuit had a little logo on it of a B. My immediate thought was that it is by Banner. Weirdly though i can not fathom why my brain just decided this. So, does anyone recognise the logo???

The bathing suit looks 30s maybe early 40s to me, wool was popular in the 20s/30s and that might be some sort of team logo.
