Mrs. Monkey inherited a gate leg dining table when her grandmother passed. Unknown age and origin. She says it's been around as long as she has so at least 50 years. The only markings are underneath the top. I've attached a photo. It's seen quite a bit of wear over the years and I was hoping I could just give it a light sanding throw some stain and sealer on it and call it good. Any information would be appreciated, Mrs. Monkey would be less than pleased with me if I mess this table up.
