Recommendation on operator

Question

Good day, attached are photos of my operator that has broken. I believe it's an old Anderson from 1963 it has glazing on the outside panes of glass so it's original. The arm is about 9 1/2 inches in that realm.. I have four of the same units two are right and two are left out on the set of windows. Thank you for your help and I look forward to your response. I have installed these before but I wanted to double check on the replacement unit for this project.
Sincerely
Peter

Thanks for reaching out! Given the measurement of the arm, it appears you may have older version of the 39-027E and its opposite part 39-028E. To confirm that this is the correct replacement, carefully review and compare the measurements from your existing operator to those shown on the diagram below. You'll also want to double check and confirm the wheel attached to the end of your operator.

These are compatible with the 39-114L non-folding and 39-205 folding crank handles.
