OK, it looks like the top of the base is bowed down about 5/16" at the middle. Both along and across. I'm not even going to try pulling it flat from underneath, it's sure to crack. I pulled the shelf out of the base, and it appears to be poplar. Nice tight grain, there's probably another project to be made from it. Wife wants an oak shelf. Options for the top are Baltic birch with veneer or just a good grade of nicely veneered oak plywood. Doesn't even need to be QSWO veneer, as it isn't now. I'll start checking prices on Monday.

Funny- I tried to remove the screws holding one of the locks to a door, as we have no key. The lighting in the garage is decidedly poor, and I kept trying smaller and smaller flat screwdrivers in the slot(s). Finally hunkered down (arthritis- I should have made sure I had someone available to help me back up, if needed) and discovered that they are nails, lightly scored! 🤷‍♂️ Vice Grips did the trick. Looks like a Paris lock, #36. I've looked online but am not really interested in buying a bucket o' keys. I do know a locksmith, maybe I could ask him, but I'm curious what kinds of rabbit holes you folks have gone down looking for keys. I could just grind the rivets off that lock, as my wife just wants simple pulls, but there is no other latching hardware to hold the doors shut, so not really wanting to go that route. I can make my own key if I cut the lock open, but I'd really like to keep it somewhat original. The key can just be left in one of the locks. We certainly don't have servants to potentially steal the silver or China. 😄
