The original selling price in Japanese Yen is often included in the model number for example FLG-90 = 90000 Japanese Yen.
The Japanese made guitar was actually a closer copy of the 1959 LP than the Gibson USA guitar being produced at that time.
The Japanese models usually had a long tenon like the 1959 LP's, and are not weight relieved, the US Standard version did not have a long tenon and is weight relieved.
The VH-1 pickups from 1987 and after are approximately 8.2 kΩ DC resistance and have a ceramic magnet and are not wax potted.
The higher end Burny guitars have fret edge binding and most models were finished with a thin polyurethane finish with only a few high end models having nitrocellulose lacquer finishes.
