You will have to provide the name of the maker.
you would need the model number as well as serial number.
Would need the model to answer.
You can look up serial numbers at Proofhouse.com
It sounds to me that you have a Model 1908 hammerless model in .25cal.your serial number would indicate that this pistol was made in the year 1919.
It would tell the year when it was produced.
Would need to know the model to answer.
Would need model name to answer.
that would depend on overall condition and when it was made. by furnishing the serial number it can be determined when pistol was made...............
Would need model name to answer.
You probably have a Mk. I pistol, manufactured circa 1958. If this is the case, it would be a semi-auto pistol, chambered in .22 Long Rifle.
about 1920 the value would depend of overall condition of pistol.
Please,when asking the age of a colt ,just giving the serial number is no help.Also needed would be the model name,if possible.
