I am looking for some suggestions and possible references to assist with identifying a pair of artifacts (believed to be parts of one object originally). For context, these were collected from a site dating to the late 18th or early 19th century with a historic First Nations association in Alberta. They may be from that period or slightly later (possibly as late as early 20th century). We have gone over a number of possibilities but haven't been able to establish a certain function or identification for these,

Thanks much!
