Below is an image of the markings found on the left side of the
slide. They are standard Star markings found on most pistols. Just
below the slide lock is the importer's stamp: Firearms Int'l Corp.,
first inspection there was no apparent Year of Proof stamp on this
pistol. When the pistol was disassembled it was discovered under the
left grip panel and is shown on the right magnified many times. From
top to bottom, the markings are:
1. Late Eibar House Proof. Mark of admission to proof. Used after July 9, 1931-present.
2. Late Eibar Automatic Pistol Proof. Used after December 14 1929-present. This was struck on the pistol after it had been fired four times with the type of powder standard for the gun. The first two shots were proof loads which developed a 30% pressure surcharge, while the second two shots utilized standard cartridges to verify function.
3. Year of Proof Code O*1 signifying proof in 1970.
The butt of the pistol frame is marked in the standard 'late' Star
manner, that being the model designation stamped to the rear of the
magazine well. The magazine floor plate can also be seen in the picture
with the importer's stamp on it.
stated in the opening the main difference between the 'A' and the 'AS'
is the magazine safety. On the left you can see how the magazine safety
works. If you look about 2/3 of the way up the magazine safety you will
notice a small 'arm' that protrudes into the magazine well. When the
magazine is inserted it pushes this 'arm' out of the way flexing the
magazine safety outward (it is retained by a slot at the bottom). This
moves the magazine safety out of the sear bar's path of travel. If the
magazine is not inserted the magazine safety is on the same plane as
the sear bar and blocks it's movement to the rear precluding its
interaction with the sear proper. You can also see the
interrupter/disconnecter in this photo, which rests in a small recess
in the slide when disengaged (as in this photo). When the slide is not
in battery the interrupter/disconnecter is pushed downward. This moves
the sear bar below the level of the sear and precludes engagement and
release of the sear.
