The photo angle is from slightly below, which may give the appearance that the bow is not as bowed as it should be. Best way to know if it is a good buy for you, is to try it and find out. Trying, does not mean buying.
Looks like a typical German-made factory bow. These are usually a little on the heavy side. Some are quite good and worth the money providing there aren't too many repair issues. Give it a spin and go from there.
