3S is an old standard and existing 3S shutters are rare.
Please check the compatible lenses yourself.
This item is stamped with "No.3".
However, that is because the screw standard
for No.3 was changed a long time ago.
Shutters before the new No.3 standard were sold as No.3, and later,
to distinguish between the new No.3 and the old No.3,
the old No.3 was renamed No.3S.
