Snack tray and coaster set 6 trays plus carrying caddy

Vintage wooden snack tray plus carring case. The poor little thing needs some help. One knob is missing. There are 6 trays. They need a good cleaning. Then on one side the wood has split and the nail is exposed. Now the good news these are scarce. I have found only one other one. The best parts of these snack trays are still intact. The hardware is amazing. Real Metal. Heavy hardware. Such a beauty! Just needs don tlc.
