Wow, Damascus [Ernie] thank you. I had not seen the hole before. I had stared at this which came with some fine tools in the compartment that is not uncovered in the case. It's preciseness was not in keeping with the rest of the tools. Then it dawned on me that it was not a turnscrew, but a tool to remove the forend pin . It works and fits perfectly and I wondered why we never see more of these. It is always hard to remove the pin with conventional tools without damaging the surrounding area of the pin. Then, with the unusual curved handle, looking like it might assist in pulling out the tool after pushing the pin, I thought I had the answer. Your thought is much appreciated. Have you seen others like this ?
