Hi all. I came across an old 22 that had been painted and looked used and abused. Taking in these kind of strays as I am known to do at times I need some help with trying to identify make and model. After stripping the paint off of the barrel and stock I found the following mark on the barrel. It is a triangle with a slightly smaller triangle just inside that like a border. Inside of that is a circle that touches as close to the 3 corners as you can get. Inside the circle is a large T. I tried taking a picture of it but it is so worn you couldn't make out the details. Anyone have an idea?

really pictures of the whole gun not the markings would be a great help.
