bausch & lomb scope 2 1/2x power worth anything?

I also found a bausch & lomb scope 2 1/2x power scope it has been used and has some scratches on the outside of the tube. the inside looks good and it has fine cross hairs in it. It has no knobs on it just flush fitting screws on the side. It is 11" long any info on how old or its $$$$ thanks -Rob

The eyes of the hunted are on the side of their head,... the eyes of the hunter are on the front. What do you mean that I am not supposed to hunt?
