Truth single arm operator sill mount

Question

There's no number on the arm itself,  just on the bottom of the crank.  And it has the plastic slider on the tip that I can't seem to find a match for.

Hey there. Looks like you might have the 39-449 Single Arm Operator. Please compare. For a shoe that attaches to the end, see the 39-529. For new covers and handles, see the 39-375 or 39-451, depending on the style you prefer.
