Matthew My Friend-
Title-
Differentiating I From J Frame
a) I frame: Five screws, short cylinder ( I believe in your case, chambered for the
.32 S&W cartridge), and strain screw on the frame.
b) Improved I Frame: Three (or Four) screws, short cylinder, with NO
strain screw.
c) J-Frame: Three, Four, or even Five screws, longer cylinder, NO
strain screw.
For reference: S&W .32 "Hand Ejector" Series:
a) .32 "Hand Ejector" 1st Model Double Action Revolver commonly
called the model 1 or the Model of 1896; built on the I-frame.
b) .32 "Hand Ejector" Model of 1903; or commonly called the .32
"Hand Ejector" 2nd Model; built on the round butt I-frame.
c) 1st change- .32 "Hand Ejector" Model of 1903; built on the
round butt I frame with
five screws.
d) 2nd change- .32 "Hand Ejector" Model of 1903; also built on the
round butt I frame with five screws. Designed much like the First
Change model; with only minor changes.
e) 3rd change- .32 "Hand Ejector" Model of 1903; also built on the
round butt I frame with five screws. Designed much like the 2nd
Change model; with only minor internal changes.
f) 4th change- .32 "Hand Ejector" Model of 1903; again, built on the
I frame with five screws. Designed much like the 3rd Change model;
with only very minor internal changes, and identical in appearance.
g) 5th change- .32 "Hand Ejector" Model of 1903; yet again, built
on the round butt I frame with five screws. Designed like the 4th
Change model, with
major internal changes in the trigger,
hammer, and sear; with two-piece extractor rod, blue or nickel
finish, service or target sights. A small S&W trademark is found
on the left side of the frame, with a few having the trademark
on the sideplate. Manufactuered from 1910-1917.
h)
.32 "Hand Ejector" Third Model a double action revolver
built on the I frame with five screws. Cylinder had a nominal length
of 1.25", service sights with round blade front sight; a new hammer
block arm was also introduced on this model. Heat treated cylinders
began in 1920 with S/N 321000. Identical in appearance to Model of
1903 Fifth Change. Serial number found on the butt, cylinder, and
barrel. Manufactuered from 1917-1942.
i) .32 "Hand Ejector" (Post War) Pre-Model 30; built on the round
butt I frame with five screws. Its reported that the upper sideplate
screw was deleted in 1956, at S/N 640980; however, examples are
found in upper serial ranges
with the fourth screw~! Dates
of manufacture ran from 1946-1960.
*FootNote- this pretty well covers the S&W pre-model 30;
and I'm sure that my friend Old Fuff will be along shortly to
take it from here.
