[2011 J-45 True Vintage neck marks]

Southern jumbos have binding on the neck too. This guitar is just a J45 with parallelogram inlay. Maybe a special order.

[Chicago Music Exchange (CME)]

I’ve bought 2 vintage guitars from there. Not the cheapest but I don’t believe as high as like Norms either.  Their vintage inventory is great quality (which you have to really be careful of). The last time I do recall they honored holiday pricing for me after it expired (13% off). Walked out with a killer 1955 LP Junior and I got to actually compare 3 of them from the same era.

[Gibson Vintage Reissues Made For Japan]

There definitely is a Japanese market and it could just be arranged as a bulk order going overseas.
