Dining Room Table and chairs

This is a fantastic solid wood (maple or pine?) table and 4 chairs. They have always been together (30+ years) but I’m not sure if they were built as a set. Probably Amish made in Canada, based on other items we received at the same time. The table is 1.75” THICK wood with a leaf that is the same thickness!! There is a locking mechanism to hold the leaf in place. The top has many dents and dings (soft wood) and some water marks (could use a refinish to correct) Chairs are also solid wood but some are loose and need to be re-glued to tighten them up. Table with leaf is 72” L x 42” W x 30” H Leaf is 11.75” W
