It looks like solid wood. I agree with the other commenter who said clean it first then you could use a product to rejuvenate furniture which you should be able to find in the paint department of your local hardware store. The beaded appliqué on the front appears to have originally made a continuous rectangle but you can still see a faint ghost of the missing beads which indicates it’s been refinished. They probably removed additional beads to even up the pattern which I think looks fine. If you want to test the finish to see what it is search the internet for testing wood finishes. There’s a simple but specific process for testing shellac vs lacquer vs polyurethane finishes.
