The rifling on these can oftentimes be very worn, so that would play a factor. In my area, its hard to find one under the 350/400 mark pricewise. Seems like most are priced in the 4-600 range. Condition is everything on these (as usual). Ive paid 100 for a parts only gun (missing follower, cracked stock, etc) and that was about what I got for it when I sold it. I have seen extremely nice examples break $1000. It is not a particularly rare gun, I see them at most every gun show and they often pop up for sale. You should be able to find a very similar example of whatever condition you have on gunbroker's closed auctions. They are fun guns to shoot. Best wishes. If you post some pictures, somebody might dare to give you a better ball park.
