As soon as I can upload a photo of the sharpest edge ... but maybe I have not raised my question well. My question is if this ludwig is authentic ... I think so but I would like some ludwigs expert to clarify ... Greetings
Not quite sure what you mean by "authentic" here. Yes they are real Ludwig drums, yes they are from the Monroe, North Carolina era. Yes they are from the early 1990's judging by the ink date code stamp inside one that you have pictured, and by the looks of it, they appear to be six ply shells, so that would make them the Classic Maple series shells, as opposed the Super Classic shells, which are 4-ply and thinner than these 6-ply shells.
This era of Ludwig drums are considered "modern" drums still, not really vintage, so there really would be no reason for anybody to counterfeit or replicate them, simply because they are just considered "used" drums, and don't have an extremely high resale value. They are good quality and sound great, but they are not worth someone's time to make counterfeit for the reason I stated above.
They look to be in great condition, so just set them up and enjoy playing them. Cool1
