You must identify the manufacturer of the gun to be able to determine the date of manufacture. If the lettering on the barrel says "38 SW CTG", then look on the underside of the barrel. If you find the word "EIBAR", then the gun was made in Spain sometime between about 1910 and 1935 by any of the small gun makers in the Eibar region of Spain. Value is maybe $150 in good condition on a good day.
