This was a builder grade window on the west coast for a home built in 2005. I am unable to determine the manufacturer but I was able to see part number 32062 stamped into the arm. Looking to purchase replacement part. Thx

Hello,
Take a look at the 36-049 hinge set with a 14" base to replace the top and bottom hinges of the window in your photo. Thanks for posting!
