This does not involve Bradley University, but involves two other BU's-

Baylor University is suing Boston University over Boston University's use of a BU logo that uses an "interlocking B and U".
Baylor claims they have used that style logo "since at least 1912", and it was trademarked in 1987, although there are significant differences. The Baylor logo is green and yellow, while Boston University's colors are red and white.
These are the long-standing logos used by both schools's athletics-

But Boston University has been using a different logo with interlocking B and U since 2018 on hats, apparel, and other merchandise-

Has Bradley ever used a similar "interlocking B and U"?
I have looked through all the things I have with the Bradley logo, and didn't find any that had the interlocking letters. But I wouldn't be surprised if it was used at some time in the past.
