Learn what to buy before you start buying too much. A short list should include small bore 16 and 20 Foxes, Smiths, Parkers or good condition Lefever Ds Smallbores. Nobody every owned too many of them. Buy condition over name or shine. Others on here can explain features to look for or entire guns to avoid. And always remember guns are a hobby not an investment so buy what you like to shoot not what you hope will go up in value.
