I believe it’s basically a Model A Ford emergency brake, so you may try researching that.
Also, make sure you have the shoes pinned on the correct end. If you pin the front as the wheel rolls when you apply brake it tend to will drive the brake into the drum. I had this problem after a brake job and changing the pin location fixed it.
Thank you for the information.
