The early kits had the modeler glue in the hinges. Later kits had the hinges glued from the factory. If you tug on the control surfaces and they don't easily come out, then you've likely got the pre-glued ones.

A really good pull, but not hard enough to break the wood, will show you if you have the glued or not-glued ones. The not-glued ones just had the hinges inserted into the slots. A light tug would pull the surface free of the wing, stab, or fin.
