Zach,
If I were you I would repair & keep the bag that's on it, as appears to be the original bag. As for the tools, I agree, they look like they're in fine condition. However, I don't think you're missing a wand. In the early to mid 50's Royal sold an economy attachment set and a deluxe set. The economy set had just what you have there--hose with adapter, one wand, dust brush, crevice tool, and upholstery tool. The deluxe set also had a second wand, floor brush, and a caddy instead of a box.
