My Andersen part is marked 135143-L. It is approximately 29 to 30 inches long depending if the on how the locks are switched. It's for the left side of a casement window

Thanks for reaching out to us. Based on your photos, I recommend our 38-147 and 38-148. Look these over and let me know what you think.

I have a similar component, labeled 135143- with the "L" and the "1" below, exactly as in the picture.

My tandem lock, however, is 26in not 29in. I can't find parts anywhere that are of this length. From my search online on AndersenParts shows there are two different models that use the 135143- mechanism. A standard/short model, which is 29in, and a long model, which is longer for taller windows. No luck finding something shorter (26in).

Any idea where I can find such a part?

Thanks for your patience while we looked into this. Unfortunately, we've been unable to find a shorter version of the 39-147 and 39-148. I actually thought that this was the short model, itself. I was not aware of anything even shorter and have been unable to source it.

Either way, this is the smallest length we can offer. I am sorry for the inconvenience.
