I'd contact Daisy directly and put in a request for one.
I've gone through several air gun catalogues and have been unable to locate a Daisy model 170 bb gun that has ever been made. I did find a Daisy BB gun model 5170 and a BB rifle model 1170 along with a BB rifle model 107 but "NO" model 170. However I suggest you search the web for "Daisy Air gun Repair" or "Air gun repair" and locate someone near you who can help you.
Daisy never made a 1000 BB gun (that I know of) however they made several versions of the Model 1000 BB rifle. Your best answer should come from Daisy. They offer a free service to tell you about your old Daisy. See the link below

I would suggest an AirSoft BB gun. Not a Paintball or steel BB gun. Unless you have someone who is familiar with firearms then I would get him a Daisy Buck BB rifle and an adult to teach him the respect and rules of handling the rifle. The "Daisy Buck" is designed as a starter BB rifle for youngsters.
