At least they are made of proper tree wood, to preserve it I would go for a proper and careful sand down, new label and a satin finish (danish "oil"?). That will preserve the wood, show what it was and be easy to clean. Not that many were made and I am sure as soon as possible they were replaced with a better set and not "loved and enjoyed". A like new look would be more historically accurate. On the other hand many would have made the way to the shed. like my grandad had, and been splattered with paint etc..
