Duel armed casement window operator needed

Quick Learner from Tacoma, Wa
Just wanted to make sure I'm ordering the correct part. The only markings on the old unit are the date on bottom "04/24/17 18:31 A" and "Truth" under the crank mechanism.
Do I need the left handed unit? Window opens to the left from the outside.
Thanks,

Janna

Hi Janna. This looks like the 39-253RB Dual-Arm Operator. This is technically the right-handed operator: Truth determines this from the outside of the window looking in. At any rate, you can tell it's the 39-253RB you need from the position of the spline the crank handle attaches to--it's on the left side of the operator body. With the 39-253LB, it's on the right-side. 

For a new cover and handle, use either the 39-376 or 39-452, depending on the style you prefer. Also see the 39-529 Track Slide, which is sold separately. Let me know if you have further questions.
