Vintage Wooden Date Calendar Blocks and Holder

Found these in an auction box I got, they were not my intended purchase, I didn't realize they were there until I emptied the box. They look like a little desktop calendar set, where you can turn the blocks to change the weekday, date, and month. They are worn, some sides have more wear than others, still very decent and usable condition. Selling AS-IS and we do not offer returns, so please view pictures carefully and ask any questions before buying. I would be happy to take more pictures upon request, thank you! This set measures about 7 inches long, 2 and 1/2 tall and 2 and 1/2 wide when all blocks are inside the case/holder. Will consider any offers.
