Andersen hardware and random glazing stop at 19 1/4"
I need a few cranks and a few lock arms.
Thanks for reaching out! The stamps from the first photo appear to be from a window hinge. I believe we can recommend a replacement for the ones you have but I'll need to know the measurement for the length of the track installed to the window sill.
We do not have a direct replacement match for the glazing you have but I believe our 55-015 could possibly work for you (also available in a 3ft length 55-015-3). They are the closest match.
The Andersen operator you have reminds me of the 39-264 Andersen Split Arm Crank, which is used along with the 39-152 Andersen Classic Operator Cover and the 39-286 Casement Window Handle. The window lock reminds me of the 38-285 Andersen Lock Bezel used along with the 38-291 Andersen Lock Handle.
Take a look over the dimensions to confirm that these are the correct replacements for your repairs.
