Identifying the right Window channel balance

A home owner from Portland says:
I need to replace window channel balances for the single hung windows(non tilt). The length of my window channel balance is 27 inches(682mm). The width and the depth is both 0.62 inch (16mm). It has a stamp, 3050. Please help.

I would like to add more photos. I think the top guide is missing as my dad tried to fix it and the broke the top guides and upper window rail when the spring soAred up... i dont even know id this part is a top guide or something else but i took a photo in different angles. The last pic is where the channel balance is supposed to be. I took this photo from upper angle. Thanks

Perhaps I can be of assistance. Regarding the broken window balance, we need to see the top and bottom nylon fittings attached to the metal channel to determine the series. Also, it's important to note that your stamp option of 3050 tells us the metal channel length should be 31", not 27". Please recheck the dimensions. As for the top sash guide, look at 18-008 and compare to an unbroken one.
