I have found different sizes of these small some what horse shoe pieces at early sites. This one is approximately 3" X 3-1/2" X 1/4" thick, some what horse shoe shaped with a cross bar. Seems to be made of iron. Any Ideas?? (Will try to give a better description as surly someone know what these are) Appear to be built heavy duty. They could almost pass for a very small horse shoe if they had the nail holes and didn't have the cross bar. The 2 ends have a some what T shape on the very end. Were found at early home sites. Would sure like to know what they are!!!
