Wait, you saw them in person but didn't play one to see what the neck was like?
Anyways, by using google:
・ Flame Maple/Mahogany body
・ 3pcs. Maple neck
・
Rosewood fingerboard
・ Edge Pro bridge
・ DiMarzio Paf Pro (H) neck pu
・
DiMarzio Blue Velvet (S) mid pu
・ DiMarzio Paf Pro (H) bridge pu
・ Cosmo Black hardware
These are also interesting in that they were apparently made as a J-Custom and then as a Prestige. I didn't find anything on neck dimensions.
