Blue Book of Gun Values
Need to know the model type to answer.
Would need a model name to answer.
colt made single action revolvers in 1884. Do you mean 1984 ????
value depends on overall condition, however, the rosco has little value...........
Assuming it is .38 caliber and therefore a J-frame, and without knowing condition, $150-$300
Need a better description. Is it a pistol or revolver? What are the markings on the barrel or slide? is it a single action(cowboy gun)? is a double action(police gun)?
25-60 or so
it was made about 1907........................
is it double action or single action ???????? value depends on gun condition
