I'am no expert just trying to help Ya, but that "might" be a Bona Allen saddle.
Did the bronc have a rider on it ? BA's saddles had rider on bronc . They also if my memorie serves me correctly made saddles for JC Higgins,Western Auto,Penneys, etc and would but slightly different type logo on -em. Sometimes with logo like riveted on I believe.
Another maker w-horse an rider is/was Seidel Saddlery however their rider was not on a bronc but a horse rearin back on its hinds like the Lone Rangers and Roy Rogers horses(names escape me) and cowboy had hat in hand over his head.
Another long shot would be the WYO Saddle comp but don't think or remember if their brand logo had a B/bronc.
Hope it helped .
