My point was that the glue lasted fifty years and was still stronger than the wood. And it was plain old Elmer's white glue. Don't know if Titebond was on the market fifty years ago and did not see it in the small town I grew up in.
I had been wondering about the longevity of glue joints. I have repaired a number of antiques with joints that appeared to have aged out, the glue just crumbled. Probably hide glue. Even though two joints failed on the clock the rest were fine. The two that failed were probably affected by the cross grian stress from putting the front of the base on as a solid wood panel.
