A question for the historians amongst us: anyone know what this hand tool was called? It "measures" 1/10 of a chain (for estimating acres).

It's the wooden triangle.  Sorry that the picture doesn't show much more detail.  It has metal points at the bottom ends that are exactly 6.6 feet apart (1/10 of a chain).  The wooden handle at the top freely rotates.  The way its used is that measure off 1/10 of a chain, pivot on one point and swing the other point forward.  It's a really easy way to walk around an open field and get a quick estimate of how many acres are in the field.  For example, 20 units (one unit = 6.6 feet) wide by 100 units long = 20x100=2000 square units = 2.0 acres.
