As far as antiques go this will be one of the easier restorations. Due to their hollow,thin wood construction, the legs and leg banding sometimes took a beating. Replacement banding is available.This can really add to the restoration cost. The legs and the aprons is what really makes these tables,so examine closely
The anniversary's rails came two ways, solid wood or a commercial Formica finish. Formica, while a durable finish, is considered to be much less desirable finish of the two. It can be a real problem to repair Formica.
Condition of metal castings. Figure cost of polishing.
Ball return? Hopefully it is drop pocket! The original fiberglass returns and pockets can really add up if repairs or replacements are needed.
Good luck!
