I recently bought a screen used Universal Solider headset. One of the parts on the headset appears to be a model part, but I have not been able to ID it. Looking for some help from you! It appears the model part has had some pieces added to it... primarily the block at the bottom, but possible the cone shape as well. It has been cast in metal (it is a counterweight for the heavy eyepiece on the other side of the headset).
