Josey-
I'm not really sure which S&W .32 caliber "Hand Ejector"
series you have? You see, from 1906-1909 is where the
serial number you indicated (944XX) falls; and this would
be from the 2nd change.
But, in more modern times the model 30 was produced
from 1948-1976; with your 3" barrel version becoming a
standard in 1957. Also, prior to 1957 these guns were
known only as the ".32 caliber Hand Ejector" series.
Begining in 1957, the model 30 designation was given
to these weapons; which was followed by the stamping
of the model number.
The J-frame production did not began until 1961, at serial
#712954. In 1969, the letter H was designated to preceed
the numerical didgits. Finally, in 1976 all model 30's were
dropped from the Smith & Wesson line.

I have my father's S&W model 30, which is a 2" pinned
barrel, blue, six-shot .32 caliber "Hand Ejector" with the
H serial prefix. I bought in NIB for him in 1971. This gun
is now a "safe queen" among other treasures.
