Q

I recently inherited a Smith & Wesson
Model 10-7 revolver chambered in .38 Spl.
The markings shown on the gun leave me puzzled. The backstrap is stamped " RHKP 1759. " Stamped on the butt of the grip is
" AAM7024, " and there is lanyard ring. The cylinder's crane reveals the
model and another number " 42917, " which, if I had to guess, is the
serial number. I've been going in circles trying to find information about this
revolver. What have I been given here?

QUESTIONS & ANSWERS

Your reference to the revolver's model
number is correct. It is a Model 10,
which, prior to 1957, was known as
the .38 Military & Police. The general design
dates to 1899 and represents the longestrunning model produced by S&W, and not
surprisingly, it has also been produced in the
greatest numbers. The frame size is denoted
as " K " and corresponds to medium size. In
this case, it can also be referred to as the K-frame service version, meaning it
features fixed sights rather than the adjustable type as on the target models.
The " -7 " in the model number represents the seventh engineering change to
be incorporated into the design since 1957. I am not sure of the current " dash
number, " but believe it to be in excess of " -14. " The " 42917 " is not the serial
number, but is more likely an " assembly number " used to keep critical components matched during production. The serial number is actually found on the
butt. In 1982, the pin securing the barrel to the frame was eliminated, and a
three-character alpha prefix was added to serial numbers. These two features
will date your revolver to 1982 or later.
Because of the popularity of the Model 10 with law enforcement entities
around the globe, there is a subset within the collector groups of guns that
can be identified with specific agencies. In this case, " RHKP " stands for Royal
Hong Kong Police. The " 1759 " on your revolver is a " rack number " or some
means to maintain accountability. Other features include the standard-weight
barrel and lanyard ring. This version was produced around 1983, apparently in
large numbers. According to Standard Catalog of Smith & Wesson, 4th Edition,
by Jim Supica and Rick Nahas, some 13,000 of these models were offered as
trade-ins for new firearms, and were acquired by the Accusport company for
sale in the United States.
In addition to the above information, I also notice that a prior user altered
the factory stocks by cutting away the upper " horns " that extended to the
hump behind the hammer.
