does anyone have any input on this bow its my grandfathers old bow and i have no idea how good how much its selling for etc its called a black hawk avenger???

Looks like the string is too short.

Definately a recurve, and looks like the string is too short to me also. I haven't been able to find anything specific on that bow, but back in the day there were lots of smaller companies making them. My guess is it will be worth a lot more to you because of sentimental reasons that it would be to a collector--but I could be wrong there.
