This item was used at the Waddell Factory in Reed’s Point. One item is made of wood, and the other of iron. They are identical otherwise. Could it be some kind of comb or stencil? There was also a sawmill and gristmill at the same location, so this item may have been used there as well.
One member has suggested that this tool may have been a guide for making furniture, possibly for dovetail work.
It has also been confirmed that the wooden object was used as a pattern for making the iron version, as slight irregularities are identical in each.
