HELP!! T206 set - 8 Variations question

[FFIMARRIOTT]

So there are 525 cards in the T206 set, noting the “Big Four” and the Cobb back. Without these, makes the complete 520 card set; am I correct in assuming this thus far?

Of the 520, I have 512 cards, and a few of the ones noted below. But I thought the below are all variations, and, that they were not part of the set (So I didn’t factor them in)…are they? Do I need to get the ones that I don’t have below also?

• George Browne (Washington) Var. – have
• Dahlen (Brooklyn) Var. – DO NOT have
• Demmitt (St. Louis) Var. – DO NOT have
• Elberfield (Portrait) Washington Var. – DO NOT have
• Kleinow (Boston) Catching Var. – have
• Lundgren (Chicago) Var. – DO NOT have
• O’Hara (St.Louis) Var. – DO NOT have
• Frank Smith Chicago/Boston) – have

Please let me know if some, none, or all of the above is correct. Some of the noted variations are big bucks, and again, I didn’t think such variations were part of the 520 card “set”. Thanks!!
