Please identify our sash support. The engraved numbers are F 21 12 26 7, Anderson Corp., Bayport, Minn. It is approx. 7 1/4 inch in length and 2 3/4 inch wide.

In the corner of the window on the glass is the number 11 on the left side of your A/W logo and number 72 on the right side of the logo. At the tip is XI.

Thank you
