Estate find. Here we have a folk art carved carpenters chalk line tool in the form of a family of Martens. Baby marten lifts up to expose the chamber for the lump of coal/chalk for the line running from the spool. Has what appears to be a bone carved alligator attached at the front end of the line to be used for pulling out the chalked line thru the camper pot. Great find, not used. And the 3 Martens are just unreal. Sold as is as shown.
