I'm posting this on behalf of an internet acquaintance from Canadian gun forum. It was his grandfather's gun but beyond that the history is unknown. This front sight is smooth on the opposite (left) side. The wooden device was formerly strapped to gun with leather however the strap now detached. Whether the owner competed in shooting sports is speculative but seems likely. Am wondering if anyone has seen something similar or can shed a light?
The gun itself is an EC Green with T. Conway of Manchester address on rib
