This could be an interesting gun. By its serial number, its an original Model of 1902.
It should have a straight-taper barrel, with no shoulder on the barrel where it meets
the frame. It is the first K-frame model with an extractor lug under the barrel. This
is probably a 1903 gun.

A couple of pictures would be very nice. What is the barrel length, from the front
face of the cylinder to the end of the barrel ? Most importantly, what is the sight
configuration : adjustable, or fixed ?
