The erroneous vintage/modern neck diagram is from Dr.Nitro. He seems to know more than a lot about vintage Les Paul. It would surprise me very much if he is wrong!A glamour shot of your Historic(s) is typical of a first post. You decided to get right into talking about what can be improved. That is fine. My objections and I believe most of the push back you received happened when you began posting completely erroneous information as fact. That vintage/modern neck diagram sketch you posted appears to be an absolute fabrication which you should take down for integrity’s sake.
This community is served by good and honest debate and the freedom to disagree even vociferously is beautiful thing particualry in today‘s day and age.
Btw, Sounds like a wonderful wife. A 59M2M should be a fantastic Les Paul. Please share some photos of it with us on the board.
