Went out looking for threadless in Bowmanville ON and instead found an old utility line running parallel. In the ground were this 162.4, a 164 and two frog eyes (clear) all in a row with the crossarm having rotted away leaving only the oak pins and the metal cross braces. Here are the 162.4 and 164 cleaned up [id=403819924]. That's the bolt that held the cross brace to the crossarm to the right of the pin.
