Well I thought the inlet at the back of the lock looked a bit diffrent. And when I said it was out of Kentucky, That is where I bought it. I had a hunch it was from Pen, but it was just a hunch. I nerver had plans to do anything to it. I bought it because I liked it and the not the worth of it. BUT if it had well known maker that would be great!!! and if it doesn't to me it's still a great gun. I don't do it for money as I'm sure you guys do this becauce you love it too.
