Bought this dining room set from a couple whose great grandparents had it. Supposedly bought in the 1940s. Me and my wife can't find anything on it and would like to know exactly what it is before we start to refinish it. All the chairs have a #62 on them with a letter from A-F. The table has a 3 and 75 stamped on it. The buffet has a 286 stamped on it. Any guesses on what this could be?

Thanks!
