does it look like this?
if so, like C3 said it was made by high standard. i think early ones were high standard model 200's & later ones were flite kings, but i think the only difference is the vent rib barrel on the later models. in my opinion they are really nice guns for the money, i paid $99 for mine a couple years ago.
i'm not sure about choking it though, that may be a question for a gunsmith. from my research online, some say a smith may have to look at it in person to see if the barrel is thick enough at the muzzle
