Need info on an Ithaca Double Barrel Shotgun

thanks do all of you for your replies. I had no idea that gun was that old. It is not pitted inside. After my father died I took the gun to a gunsmith (10 years ago) to see about getting the barrell re blued. (or whatever you call it) He advised not to do this. Instead to take a burlap sack and oil and rub it over real good. My boyfriend did this, and cleaned it. It has been in my living room ever since.
I talked to my brother in law today who had used it to hunt with. He said it shot real good. Daddy used to hunt quail with it all the time. But after listening to what you guys say I would be afraid to fire it. I have a 38 colt pistol that is loaded with bullets. It belongs to a friend who lets me keep it for self defense here at home. I had taken a conceal carry course here in NC and learned to shoot the pistol. But some guys at work told me the best defense at home if anyone broke in at night would be a shotgun. They said it would be harder to hit someone in the dark with a pistol. As for ratshot for the pistol, where do you get that? Also, if a shotgun for home protection, what kind would you suggest? I need something reasonable.
There have been alot of break ins around here, people killing people, etc. There is alot of gang activity around, although not right here in my neighborhood. Still, you never know.
I thought of making a sign and putting on my door that says,
"Protected by double barrel shotgun - come on in!" :wink:
Also, any more input is greatly appreciated!!! Thanks.
