I am also doing the stabilizer but I do not recognise your problem. I am going to remove all the metal fittings and will check the glue. As my stab never had been repaired it did not have any fabric. I chould see all the military paint layers down to the plywood. Olive drab and Neutral grey. I don´t know if the UC61A intended for the Eropean WWII was treated different. On the underside it still had all the drain holes still open.
I made an unseintific test. I atached the stab on the bench at the stab-attach points and sat on the tip. 210 lb. I did the the test by ataching the stab under the bench and with the same load. I chould not hear any cracking or other noices. It deflected only a 1/4".
If normal or not I don´t know. It must stand 3.8 g.
on the max down load and weight of the tail.
