The 0001 is not a gibson serial number, that's not where they put it. It's a post 1970 -ish reissue double cut junior, all of them were mahogany, possibly Cardinal Red, that was a color they did back then. No hybrid or custom body or prototype about it. The weird routing for the pickup is just that, some weird routing, possibly some Kahler or other type of trem bar that people put on them back then. Maybe, I'm not saying it is, I'm saying maybe.
Might be hard to see, but serial should be on the back of the headstock. Sometimes the paint is a bit thick up there and fills it in. Some guitars of that time(approximately) had stamped serials, and that may have come and gone if it was one of them.
