Where can I find and an Annie Oakley Commemorative Rifle for sale under 1500?

Good luck with that. There were at least 2 different Annie Oakley Commemorative 22 rifles- one by Winchester and one by Marlin. New in box unfired (normal state for a pure collector's gun) is running about $1500 and up. Your best bet may be to check on line auction services, such as gunbroker and gunsamerica. Bear in mind that despite much misinformation, any firearm must be shipped to a dealer in your home state, who will charge you for doing the transfer paperwork the same as if you bought in their shop.
