Made by Leinad Inc. in Ducktown, TN. Phone # 423-496-7060.
A typical starting load for the ball and cap Leinad pistol would be about 15 grains of fffG powder.
This would be a Browning Challenger .22 pistol made in 1970.
You can look up serial numbers at Proofhouse.com
Would need the model to answer.
would that be pistol or revolver...........................
It would tell the year when it was produced.
You will have to provide the name of the maker.
Would need to know the model to answer.
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.
you would need the model number as well as serial number.
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.
that would depend on overall condition and when it was made. by furnishing the serial number it can be determined when pistol was made...............
