I scanned up a few dozen pieces by this publisher this weekend. Most are in C notation. Despite some having racist titles (to be expected) these are very playable and entertaining. Not too hard, not too easy. Kinda in that just right place.
I did not think to add the publisher in the tags so you will have to dig through. There are a few small folios "Choice Selections for Banjo". I'm hoping to come across the rest of the titles and folios in the stacks.
Anyway, take a look. At the very least it will be a good way to spend an evening playing through them.
