Pottery Barn Kids Wooden Alphabet Abacus Learning Toy

Wooden Alphabet Abacus. So cute! Wooden pieces swivel on dowels. Letters with corresponding words/pictures on flip side. Good conditon with scratches and marks from normal wear. Zebra has pencil marks on it(I didn’t try to remove). The dowel across on the back is missing. It doesn’t affect the steadiness or balance of the abacus(see last 2 photos). Not sure the brand. It looks like the pottery barn kids abacus, but there is no marking/brand on it. Approx dimensions: 15 1/2”W X 17”H X 8”D
