I don't think so? Look at this one that my friend found, doesn't it look like a neck through?

Greetings from Sweden!
A friend of mine happened to buy a Rickenfaker this weekend. Is it possible to determine a maker? He describes that the neck is good quality but tuners and pick guard are of the cheapest possible sort. (I haven't seen it my self).
All the best!
