In that picture, the lower pair of grips is not factory, and the upper
pair is from the 1930 to 1940 period. If your gun is from 1922, those
are not the right grips - they are 8 years before they were made !
These guns are the model of 1905, of which the serial numbers run from
about 63,000 to 1,000,000 . So yes, they made lots of them. Of course,
this large number includes all barrel lengths, two finishes, two sight
configurations, and the K-32's and K-22's.
