Nice Kennie!
That machine would be from the mid-to-late '70s, and it's upper-MOL, like maybe one model away from the TOL. You should be able to put together a set of tools pretty quickly, they're all over the place. They're white plastic or white rubber, depending on which tool you're talking about, and the dusting brush has a swivel neck on it, which is really nice for dusting bookcases. There's a little round Sears logo moulded into each one.
The machine would have had a floor tool, a crevice tool, and a dusting brush. On some models, the crevice tool fit into a little slot on the side of the machine, and some models use one crevice tool, and others use another. If you have the crevice tool slot, it may take a couple of tries before you find the correct tool that fits properly. The floor tools and dusting brush were the same for all MOL and TOL models.
