I'm about to amend their Feb. 28, 1929 bout @ Tulsa to Feb. 20, per a CNA. I also checked my contemporary newspaper source, and saw no mention of a Feb. 28 bout between the two - which doesn't mean it didn't happen. But this appears to be an incorrect date, unless someone else can confirm otherwise.
