I think you did well to "miss" buying the last set of collar tabs. I believe they are fake fantasy tabs made from fake cap insignia. I suspect these are from the same source as the fantasy Police Panzer collar tabs of the same style with Pz skulls in the center. I saw a set of these sell on Manions for good money but I would not give a thin dime for a set. I have never seen a period photo of anything like these in wear and they are certainly not regulation collar tabs.
