I have (2) Windows with no labeling

A quick learner from Quincy, MA says:
I have (2) windows with no labeling and the gears are stripped and I would like to get (2) replacement window cranks. I think that my replacement might be your order 39-187 as they look very close.

My other question is i watched the video for 39-187 and it shows the bracket being on top but with my window crank i think it is on the bottom. Is that possible?

Also can Order (2) the same type for left and right?

Thanks in advance for your help.

I agree, the operators you show closely resemble our 39-187 and 39-188. The window, operator, and bracket we showed in the video you mentioned were all just examples. While different variations (like yours) exist, the general principle remains the same.
